Yeah, I hear ya. I'll say this, however: Some may have been doing what you've been doing and trying to be polite, but something during the course of the pandemic may have made them snap. I'm not excusing it because bad behavior is uncalled for, no matter what. I'm only saying I can understand because I've been in that situation. (Actually, on both sides of the equation, too.) And I also hate that I let myself get to the point where I lost my cool.
