so today I was in the middle of making two frapps for a group of girls. I just finished making six drinks for them prior so I was happy to finally be on the last two. outta no where a coworker comes over and goes “you’re doing it wrong”. I was told by a Supervisor to level out the base and frap roast with the milk for a proper measurement but I guess that was wrong(?) she proceeds to then dump both the drinks I was working on (which was wasteful considering the drinks would’ve turned out the same regardless) and says that the recipe is on the fridge so I shouldn’t be having issues with such a “simple process”. I explained to her I know how to do it the original way but I was told to do it like this by a supervisor (who constantly nitpicks what I do). she continues to yell at me in front of these girls and my other coworkers essentially embarrassing me over something so minor. a few minutes later she came and somewhat apologized and said “as a barista trainer I feel obligated to correct you” which she does often. I don’t mind being corrected but being abrasive, nitpicking everything I do, and only bothering me is just odd. Idk how to deal with this and I feel like I handled it poorly. I feel bad for expressing my frustration but I’ve never had a coworker so aggressive over frapps before? Especially when that coworker isn’t a supervisor. I just don’t know how to properly handle situations like this at work.. especially when I’m already stressed and swamped on my bar my initial reaction is to cry or scream lol what do I do? do I just suck it up and take it? I’m kinda getting tired of being bossed around and being told 6 different things... not to mention no one in my store makes drinks the same way.
