idk, i'm not very smooth so i wouldn't be the best person to ask. maybe preface with something like i don't mean to bother you but .. and just say, hey i think you're pretty and i was wondering if you'd like to get some coffee sometime. or just offer to give her your number. idk, pulling a girl through a drive-thru isn't the easiest move. just try not to do it in a creepy way ig
godspeed, anon
