Employee games the system, people wait too long for food, people wait too long for food so they stop eating at the restaurant (this was my solution, it's fast food cutting it out is pretty much only a plus), people stop eating at restaurant so restaurant raises it's prices, more people stop going, restaurant closes.

The naive take is to think any one of these actions happen in a vacuum. Plus if this is happening at any scale at a restaurant then the manager probably told them to do it.
