The expectation of tipping at a restaurant exists to allow you to punish the employee for bad service over the course of a meal by leaving a 0% tip.
It doesn’t make any sense for a counter service restaurant or other such business that consists of a single interaction before paying, where if you receive bad service you already know that and can just say “actually never mind I’m going to a different place, cancel my order”.
