3 peeps out for a meal. Initially waiter tells them the total bill is £30. They give him £10 each. The waiter realises the bill is wrong and should only be £25. He takes five pound coins from the till. He gives them back one quid each and they let him keep £2 as a tip.
The 3 customers have therefore paid £9 each which is £27 total and the waiter has kept £2. What has happened to the other pound? At the time of writing I genuinely don't know the answer! HELP
