In the larger sense, yes the owners tend to exhibit the behaviour that of an asshole.

In the context of what the previous commenter was saying, however, the employees would have to confront the individuals bringing in the food, and for what they are paid, they might rather not bother dealing with a potentially unruly patron. The patron in this case would, should they exhibit such unruly behaviour, may still be less ashole-ish than the owners, but still exhibit asshole-ish characteristics, relative to the poor minimum wage employee who’s just trying to do their job.
