2 of them order appies, and 2 order dessert, figure on 15 minutes per course....That's 30 minutes.
4 people go to dinner....
ALL order dessert, NONE order appies....that's 15 minutes. They figure that if they don't allow the choice, people will be less likely to order appies, all get dessert and they can flip tables 15 minutes quicker.
