Equality at Its Finest
Although we don’t advocate hate, we advocate equality. It’s impossible to love everyone equally since there are so many Karens in the world. However, hating someone at the same level as everyone else? Now, that’s a lot easier to do, and that’s a skill that bartenders have mastered, at least according to the OP.
There’s probably something about serving alcohol day in and day out, that probably destroys a person. You slowly watch people deteriorate right before your eyes, and there’s always at least one fistfight that your bar’s bouncer has to take care of. People can be terrible, but if you add alcohol into the mix, people can become animals.
