3 ladies went to a restraunt for a meal the bill came to £30 so they decided to pay £10 each, but the manager feels sorry for them so tells the waiter to give them £5.00 back between them, but the waiter gives them all 1£ back to stop argumants and jkepps the other £2.00 for himself, so that means that the ladies paid £9.00 each, so 3x9=27+2=29, so wheres the other £1 gone?
