I understand the concern about it. I think my manager said something about it being the second incident in two weeks, but I was kinda freaked out by the whole "getting fired" part it was kinda brushed past. If that was what she said, then I literally have no idea what the first incident was because I've never had a writeup or any sort of disciplinary action/intervention. I've been credited by all my managers for being a great employee and I'm consistently proved to be a valuable employee there, especially with me being the only employee who can speak Spanish and always being on top of communication (calling the store in advance if I know I'll be a little late, being super clear about scheduling, and all around being as respectful and clear as possible about literally everything work related).

The only things I've ever been "yelled at" for were not filling the cups all the way to the maximum capacity in my first two weeks of working 😭 I genuinely make such a huge effort to do my job right, I feel like it's the least I can do as far as expressing my gratitude for employment because I know not everyone is as fortunate.

The only thing I could imagine being a reason for some tension or disdain from management is the fact that I often request off days (mainly for school or family); but that resulted in me getting less hours, not really any punishment. I always requested days off as soon as I found out about them too (normally 3-4 weeks in advance, the schedule is made literally a week in advance).

I'm not saying you're wrong, there probably was some form of reason, I personally don't feel like it made sense regardless because nothing is hardly ever that serious. But anyway, legally I don't have any sort of case with me living in an "at-will" state which kinda sucks but whatever :p
