Unfortunately, yes, this is common for customer-facing or customer service jobs.

People have outlandish expectations, and for some reason their motivations are that they're so lazy that "I'll take my money elsewhere!" is gone and the ego-soothing dominance display of "I'm gonna Karen this shit up!" is now the standard because people have already gone somewhere and so they can't comprehend going somewhere else.

People have fragile egos, and then when forced to look at themselves, they expect your work to be every IG filter they've ever used to fix their faces, but 10X better since they're paying $2 for it. But they want it for free anyway. People are generally irrational, bad with money, look to blame anyone else for everything else rather than bear responsibility for something as personal as how their faces look, are unable to understand the world around them or how things work, and more than ever are combative for no reason. Even trying to be genuinely nice with some people results in unnecessary antagonistic behavior.

I recommend you realize that just because a couple assholes come in each day, they don't own your day and shouldn't be given permission to ruin your day. Their days are likely shit 24/7, so if you can emotionally separate their negativity and stupidity from your life, it's healthier. Be yourself and do what you can within reason.
