A staff member at Tesco has pledged not to speak to a single customer for three months.
While this may be some a dream to some of those who work in customer service jobs, the silent treatment is refusing to speak to his colleagues.
But this isn't over a bad day at work, Lee Clark, 40, is taking part in a three month challenge for charity.

As Essex Live reports, Lee is often 'noisy and chatty' but will keeping his mouth shut for a sponsored silence whenever he's at work to raise money for Cancer Research, British Heart Foundation and Diabetes UK.
After starting his annual fundraiser at the beginning of last month, the father-of-four, 40 will end his silence on April 10. His only form of communication at the moment is through flashcards, pens and paper.
Speaking while not at work, Lee said: "It could be quite draining because you try not to slip up and try to focus.
"It can be a horrible experience but, again, I'm lucky I can put myself in that position to help someone else and I'll happily do that every single time."
“That's what gets me through, it is usually every time because the sponsored silence is a very lonely place. I feel very lonely, it is quite isolated in a sense."
But this isn't a new challenge for Lee as this marks his 15th straight year taking part in his sponsored silence.
The Tesco customer assistant from Essex has worked for the supermarket giant for 16 years and decided to stay closemouthed during a nine-hour shift that year as he said he was known as the “singing man on the tills”.
In his first nine-hour silent shift all those years ago, he managed to raise approximately £800 for the Lennox Lewis Cancer Fund.
"It was phenomenal because I've never done anything like that in my life before, so it really got me," he said.
"It gave me the bug for fundraising as well. I just saw the response as well as the love and support it brought.
“People were coming in to see me just to donate in the bucket, not necessarily buying anything though, just getting involved and it meant a lot to me personally that I brought the community together for this fundraiser. It was a brilliant experience.
“I saw the difference it makes to people and that's what I never experienced before. You’re helping someone and they're helping you, there is no better feeling than that.
“I love giving, I give what I can or where I can, supporting and helping. It’s like Christmas, you get more enjoyment out of gifting presents rather than receiving them and I get that by doing a fundraiser.”
Since 2007, Lee has either organised or participated in 108 charity events - raising a whopping £178,000 for 32 different charities.
"There are some that think I’m being rude"
Lee decides to increase the time period of the silence every year by a day.
His employer, Tesco, has recognised his hard work over the years, supporting him on its social media platforms.
He also said he saw the fun and laughter it brought to shoppers and his colleagues, to a point where they start to “miss his voice” after a while.
Lee has a board around his neck with an A4 piece of paper explaining what he is doing and who is he raising money for as well as flashcards to help with FAQs. The most common question according to Lee are questions about club cards and fuel.
“It’s just an amazing community we live in. Regular customers, my colleagues and the support that I get from everyone is phenomenal.
“It’s my 15th one, so it's quite an achievement in that sense and no one gets bored of it. They love me being quiet.
"If I’m not talking to them, they are like ‘you’re the quiet one again?’
“There are some that think I’m being rude and they see the sign and realise that I'm not."
Lee considers this fundraising event as his "worst one" as he often gets frustrated when he wants to talk to colleagues or customers but can't even make a sound.
Even though he raised £4000 for Cancer Research, British Heart Foundation and Diabetes UK, he revealed that doing the sponsored silence in 2020 was the hardest year.
The Covid regulations with face masks made it hard for the Tesco staff member to communicate since customers couldn't even lip read.
"One of the hardest things I found is when my colleagues are having a chat and I can’t even join in. I switch off, I try to zone out of conversations because otherwise, I get frustrated I want to talk.
“It is the worst thing in the world when you just want to blurt out and join in their conversation.”
But he also said he feels relieved after his shift because he loves talking.
To cope during the three months, Lee has a countdown calendar to cope with the silence.
“It is like when you go swimming and you go underwater, hold your breath and then you come back up. That is how I feel every time I finish my silence.
“Swimming all day long and I just come on top of the water to breathe again.
"I marked off for a couple of days, so when I'm feeling low I can mark off a couple of days and it is quite a relief because then I can see I'm getting to the bottom of my calendar, which is where I want to be.
"Just like I do in December, I try not to eat all my chocolates. I try and save it for a few days, then eaten and that's what I've done with my little calendar."
"Anything you raise is something more than you had yesterday"
Lee plans to do the sponsored silence next year for three months and one day.
Lee's enthusiasm for fundraisers has rubbed off on his five daughters as they are getting involved and recognised through school and community awards.
The passionate father said he really hopes and would love that his legacy of fundraising and attitude of helping people carries on through his children.
As Lee hopes to do more fundraisers this year, including running the London Marathon and climbing Mount Kilimanjaro, he wants to achieve and inspire people to feel they can make a difference.
"Anything you raise is something more than you had yesterday, so it doesn't matter what you raise.”
