AmberSpyglass. Staff don't always have to follow the rules. I think that they sometimes make them up to save themselves work. I recently bagged up the proceeds of a charity event I had run. All correctly counted into the appropriate plastic money bags, and I went to the bank to deposit the proceeds before transferring it to the charity.
The clerk told me that they were not allowed to take such a large amount, and I would have to bring it in in batches. I firmly stated that the bank was earning interest on my cash, that I was 82, and that I had better things to do than travel back and forth to the bank.
She took the bag of cash, weighed each item, and paid it into my account without another word.
Most people need cash for various reasons, even if it's just to give the children a few bob for some sweets. How dare the banks dictate to us how to handle our own money. They are our servants, not our masters, and something should be done about it.
