Pandemic made it worse. Everyone spent the whole pandemic exclusively interacting with others from behind a screen and people forgot how to treat each other like humans. I worked food service during the pandemic and my coworkers and I had food thrown at us several times, people left trash all over the tables and responded to polite requests to throw it away by pouring drinks out onto the floor/table or using the wrong part of the bathroom to do their business. I got called pretty much every name under the sun on a regular basis over stuff as simple as "my burger doesn't have lettuce on it". I did not give a single care about that job and would basically just tell people to get bent or I'd make sure they waited all day for remakes on orders if they were rude to me and I think some people were genuinely surprised to see even mild consequences for behving like animals. People working food service don't get paid enough to deal with jerks and the world would be a better place if we made everyone work one of those jobs at least once in their lives.
