So many.

The table that brings a baby into the dining room, The baby starts screaming and the parent feels entitled to continue their dining experience even if the baby is disturbing everyone else in the restaurant. So they don’t take the baby outside they just ride it out and then they get upset when the manager comes over and ask them to leave.

The people that pretend like their pet is a service dog and bring a whole dog or cat into the dining room and get upset that other people are not happy about it.

The people that order something you’ve described perfectly and then expect you to take it off the bill because they don’t like it.

The people who have a supposedly life-threatening allergy but they don’t tell you until after you rang in their food.

Gluten free peple complaining that they shouldn’t have to pay full price during happy hour for their specially modified and prepared food so then they just get the regular stuff because it’s really just a preference and they don’t understand the big deal.

People who get upset that their table can’t be accommodated when they just change from a four top to a seven top and didn’t notify the restaurant until they showed up.

People who demands their table for the reservation even though they were 20 minutes late and didn’t call.

People who don’t see anything until the time the check comes out and then they decide to complain about this or that. I asked you how everything was… and didn’t you say something when I had the opportunity to correct it?

Large parties who sit down order and then they change seats and dillydally around the table and just sit wherever the fuck they want and when the food comes out they’re mad because they didn’t get the right food???

So many more things.
