A friend of mine worked his way through college at a chain restaurant. Whenever we go out to eat at a diner or chain eatery now, he orders an extra glass of water and soaks both of our utensil sets in it, then polishes them with a napkin.
So, for him, it was six utensils, using a fresh napkin each time, that's 18 napkins before he even took a bite, and had need for one.
