Three people check into a hotel. They pay £30 to the manager and go to their room. The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people. On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person. Now each person paid £10 and got back £1. So they paid £9 each, totalling £27. The bellboy has £2, totalling £29. Where is the missing £1? 

£1 is not for me hahahahaha it's not enough for me

I got them all intoxicated and took all the money

"So they paid £9 each, totalling £27. The bellboy has £2, totalling £29." The concept of "pay" and "has" is totally different. "Pay" is like a dynamic concept showing movement of cash, but "has" is a static concept showing how much you have at a point of time. You can't simply add 2 numbers together.
