@comradeagle @matrix big same! every time someone has flirted at me in public i've always tried to be friendly and show them some appreciation for the attention, even if they were someone i was totally uninterested in. (with the single exception of that one creep at the pizza place who stole my number out of the store customer records and kept sending me creepy texts until i tracked him down on facebook. turned out he was an enormous piece of work, and sure enough already had a girlfriend who i can only assume didn't know he was texting "ur hot" "wanna fuck" to random girls; him i did try to get fired.) like sure, if they were being unwantedly aggressive or invasive, didn't take the hint to back off, then that would be inappropriate. but this chick wasn't, and christ, even if she had been, she's a fucking woman. she's no threat to you, dude. getting someone fired (especially in this economy) is the nuclear option, and it's totally unjustifiable unless the employee is betraying a position of trust or acting in clear bad faith.
creepy dude menacing you? go for it. fatass woman trying to corner you? laugh at her, shove her out of the way, and tell her to go to the gym. polite bartender boy flirting with you over drinks? at the very least let him down gently and respectfully. girl *just leaves you her number without even putting you in an awkward position socially*, totally respecting your boundaries in more ways than you have any right to and being sweet and friendly to you? fucking TEXT HER you omega-tier soycuck oh my GOD. even if it's just to say, "hey, i have a girlfriend, but thanks for the note, it was really sweet and it made my day, and if you want to get to know each other and be friends i'd totally be down for that."
(dude 100% does not have a girlfriend)
