mcr flirtation tactics?? help??

hiii i have a silly story to tell

disclaimer!!! before anyone says anything i am GAY i have a WIFE (not really my wife) but just so yk i am not interested in dudes,,, anyway

i was at waffle house at probably 3am last nite with my frenz, the server was a friendly guy he said he had been working 27 hours with only a 6hr sleeping break i was like woww that sucks

anyway after we got our foods (we were the only ppl in there btw besides one other person) the server didnt have much to do so he was sitting in the corner with his airpods in and half falling asleep which yeah i would be too lol

after a lil while he got up and started doing work stuff idk what like going over checks and stuff and while he was doing things he sang The Black Parade while he was working but like LOUDLY not a mumble it while u work type thing, he wanted us to hear him fs, then he skipped through it i think during the guitar part and started singing the beginning of Teenagers before he kinda faded off and went back to work (basic tracks probably all he knew, id be hella impressed if he sang an MCR deep cut)

so some very important context here: i was with two friends who were dressed Very Nicely but in more basic outfits while i had on like a y2k grunge outfit, thick black eye makeup, spiky hair just very alternative style, we had just left the clerbbbb thats why we were dressed up

but anyway, my question is: do we think he was trying to flirt w me or maybe make fun of me?? it felt very directed like idk im autistic so i dont always catch things like that

and to answer before anyone asks no i didnt say anything even tho i obvi love MCR i didnt wanna engage in convo i was tired and also not trying to flirt if that was his intention
