The man was amazed. He asked the waiter how it is that the waiter is so well prepared to handle every problem without ever having to return to the kitchen. The waiter answered that the owner is an efficiency expert who wanted everything to run without a wasted moment.
The man asked the purpose of the string tied to every waiters' trousers. The waiter replied that, when he uses the urinal, he avoids dirtying his hands (and therefore doesn't need to waste time washing them). He simply pulls the string, and his penis pops out.
The man asked the waiter how he gets his penis back in. The waiter replied,
"That's easy.... I use the spoon."
