His Majesty may be on the Australian dollar but cash was anything but king as Bob Katter had his tender rejected at federal parliament's cafe.
The Queensland firebrand was outraged his crisp $50 note wasn't accepted when he tried to order fish, rice and vegetables.
Staff offered to give Mr Katter his fish for free, but he remained hungry for justice.
Speaker Milton Dick jumped in to support the lower house larrikin, urging staff to take the cash.
Mr Katter railed against the prospect of a cashless society.
"If you have a cashless society the banks control your life ... you can't buy a loaf of bread without permission from the banks," he told Sky News on Wednesday.
Cash was also crucial when the power cut out in natural disasters, he added.
"You don't realise until you're caught," he said.
