Re: Not just restricted to governments
My father, back in the sixties, once received a gas bill for £0. 0s 0d and, of course, ignored it.
A reminder letter followed and then a Final Demand. So, he rang up the office to ask how this could be sorted and he was told that the computer needs to see that a payment had been made, so would be kindly send a cheque for no pounds, no shilling and no pennies.
A few days later he received a letter saying that his account was up to date.
Then in the next post a letter from the bank arrived asking him what the hell he was playing at writing cheques for such an amount.
