Input: Text: let me start off buy saying i am generally pretty happy. but when i am tired.....i am so irritable. last night i couldn't sleep and i had to wake up early the next day to buy a suit. something i'm very particular about. we went to three stores already and i was so fed up. the lady who was helping us was no doubt a nice woman but i guess it's because i was so irked by some of the smaller things she did that i had an outburst perse. i let her help is and thankfully we eventually walked away with my suit but then i turned to my mom and said some not like really nasty things. but things that if you overheard them about yourself they might sting a little especially if you thought you were doing a good job. now i've never worked i retail but i sympathize. i've heard horror stories here on reddit and. i have friends who are sales associates at department stores like this one. the woman could see from working wth me i was in a bad mood. but i'm off topic now. anyway as i was saying those things to my mom i turned around to see her walking past us. i don't know how long she had been behind us or anything but no eye contact was made so i couldn't tell how she felt. i wanted to post this here in hopes that someone who works in retail can give me insight as to how she felt because i felt horrible. i don't like being mean to people and obviously being tired and irritable isn't an excuse for being dick. but i was just trying to tell my mom that i didn't like this woman i wasn't trying to be an asshole. i threw around phrases like " where do you get off" not to the sales lady obviously but in reference to her. anyway anyone think i hurt her feelings?

TIFU by talking shit on my sales associate In Front of her.
