Efficiency

A man goes to a busy restaurant and sits down at the only empty table. As he sits down, he accidentally knocks the spoon off the table with his elbow. The waiter immediately takes a spoon from his pocket and places it on the table. The man, impressed by the promptness of the service asks, " do all the waiters carry a spoon in their pockets?" The waiter answers " We had an efficiency expert evaluate our operation and he determined that 25% of the customers knock the spoon off their tables and that by carrying a spare spoon on us, we save a trip to the kitchen and can be much more efficient."

Later as the customer asked for his bill he remarked to the waiter "Excuse me, but why do you have a string hanging from your fly?"

The waiter answered " that efficiency expert determined that we were spending too much time washing our hands after we went to the bathroom, so the other end of this string is attached to my penis, and when I go to the bathroom, I simply use the string and never having touched myself, I don't need to wash my hands."
