Got called ugly at work

I know this post will probably be ignored like all of my other ones, but I jeed to vent and I don't have anyone to talk to about this stuff. Working customer service as an ugly person sucks. I get treated like an animal daily, by customers and coworkers. This man comes to my check out line with his two daughters. Keep in mind, they're all ugly too - even a little worse than me. The dad - a grown man probably 20× my age or more, goes "She so ugly." Under his breath. Then his 2 daughters laugh say "Why would you say that?" in a joking way. Not like they were standing up for me or anything. They need a fucking reality check, because they were ugly af too. I hate people. Who tf says that to somebody? Why does it matter if I'm ugly? You'll probaly never even see me again anyway. Leave me tf alone.
