The efficient restaurant

A man decides to try a newly opened Italian Restaurant. The waiter brings him to a table, gives him a menu and leaves to get him his drink.

The patron notices as the waiter walks away that he has a spoon in his apron. In fact, all the waiters and waitresses have a spoon in their apron pockets. After a few minutes, the waiter returns with his drink and is about to take his order when the man interrupts,

"What's with the spoons you guys carry around in your aprons?"

The waiter replies,

"Well you see, our restaurant is one of the most efficient restaurants in the state. Statistically, you are ten times more likely to drop your spoon than any other utensil. By carrying one in our apron, we save over 4 hours a week of going to the back for a replacement."

The man, satisfied with the answer, orders a soup and a salad. The waiter returns in no time at all with his soup and salad. As the waiter reaches over to place the food, the man notices something very peculiar. The waiter has a string coming out of his fly. Distracted by this, the man reaches for his spoon only to push it off the table. Statistics prove to be true.

Like a gunslinger, the waiter draws the spare spoon from his hip and gives it to the man. Before he knows it, the waiter is gone.

Halfway through his soup the man gets the waiter's attention after several failed attempts. Discreetly, the man beckons the waiter to come in closer. The man discreetly alerts the waiter that there is a string stuck in his fly. The waiter then explains,

"Well you see, I have it there intentionally. Us guys, we attach the strings to our... You know... So that when we use the bathroom we can just simply give it a pull and avoid getting our hands dirty. We have saved over 10 hours a week of unnecessary hand washing!"

The man at first satisfied with the answer, puzzlingly asks,

"Okay so I understand how you get it out, but how do you get it back in?"

"I don't know about the other waiters. I use a spoon"
