A man went to a well-known restaurant and gave 10 bucks to the waiter.
The waiter was very happy and said, “Sir, shall I reserve a table for you in the evening?”
The man said in a hushed voice, “Listen carefully to what I say. Only you can save me from a lot of money expense. I will bring two person with me in the evening. Then you will come and tell us, Sir, not a single table is available, every table is booked.”
