Tale of Two Spoons

All the waiters in the fancy restaurant we visited carried two spoons in their vest pocket. We were curious and asked a waiter why.
He said, “An efficiency study determined that a spoon was the most frequently dropped silverware. So all the waiters carry two spoons to instantly replace that item.”
We couldn’t help but notice that a short length of string was hanging out of the fly of his pants. So we asked about that.
He said, “That’s another result of the efficiency study. When we have to go to the bathroom, we use the string to pull ourselves out and aim, so we don’t have to stop to wash our hands.”
We said, “It’s clear how you get yourself out and aim, but how do you get yourself back in your pants?”
“Well,” said the waiter. “I don’t know about the other guys, but I use the two spoons.”
