A customer in a restaurant drops his spoon. Immediately his waiter rushes over, pulls a spoon out of his apron and hands it to him. The customer asks him "do you always carry a spare spoon in your apron?" The waiter says "oh yes sir, this efficiency expert came in and said that many people drops their spoons and we should carry an extra to save time" As the waiter is turning to leave the customer notices a string hanging out of his fly and says "excuse me but you have a string hanging out your fly" The waiter replies "oh, yes sir that same efficiency expert said we waste a lot of time washing our hands after going to the restroom. With the string, I can go to the restroom without soiling my hands" The customer says, "I can see that would work getting it out, but what about putting it back in?" Waiter says "I don't know about the rest of the guys but I use a spoon"
