UPDATE!
Ann DMed me with her memories of the evening, which helped clarify some details for me. here's now my best attempt at explaining what happened:
Ann ordered a White Claw from me, and, thinking she was the person i had talked to in French earlier, i started my bit with "je ne parle pas anglais." and she said something along the lines of "just give me my drink, please." or something like that. i asked her "voulez-vous pastèque? pamplemousse...?" and held up one of the White Claws. she said the flavor in English ("grapefruit", i think?), and i said "pardon, en français, s'il vous plaît?" Ann said "no, just give me my drink", and i said "pardon, je ne parle pas anglais, quel parfum?" and that went back and forth 2-3 times. she got pretty annoyed by this (rightfully so! i was being pretty annoying!) and then put her drink ticket on the table, and grabbed the White Claw out of my hand and walked away
she also mentioned in her DM that someone in line yelled "no means no!" while this was happening (and talked to her later), but i couldn't hear it over the noise
@itsannpierce if you'd like, please add any other details you remember! and again, so sorry for being annoying. if we run into each other again, next drink's on me
