Input: Text: st. paddy's night, 4 bartenders,  and they're making irish car bombs every minute,  expectedly. i'm at the bar getting more green beer and the girl i'm with asks, "what's that?" pointing towards the icbs he's pouring. 

i know damn well what the recipe is, and i thought i have some report with the bartender (i go there a decent amount; i know his name, that level), so i say, "that's an irish car bomb: that's guiness, and he's watering down the jameson with bailey's.."
 i thought i was making an underhand joke to make him crack a silent smile while he poured, but he was very much not amused, and said "... that's how you make a carbomb-- don't talk shit at the {bar name}." 

i didn't actually get served by him the rest of the time there..

TIFU by telling a bartender they were watering their ICB's with half whiskey..
