There is a gentlemen’s club where the man at reception who cloaks the member’s hats, coats, umbrellas, gloves has a reputation for an infallible memory.In thirty years, he is reputed never to have given the wrong coat, hat, gloves or umbrella to any member when they leave the club.
One day, a member decided to test it out. As he left the club and was handed his coat, he asked the concierge, “How do know this is my coat?”
“I don’t, sir,” came the reply.
“Well, why did you give it to me?”
“Because, sir, you gave it to me.”
