got told “f**k you” in dt today

was having a totally normal interaction with this guy at the drive through order screen and at the end i repeated his order (grande hot americano w cream) and asked for his name and he was like “uh a name? how about FUCK YOU” and said it so aggressively. like wtf?? i was so stunned i couldnt even speak, what am i even supposed to say to that? luckily my manager was on headset and heard the whole thing and he took over and told the guy to beat it and that we wouldnt be serving him today. seriously though, if you dont want to give your name literally just say that. or give a fake one, bob works just fine!!

anyways this is just the first name anyone has outright sworn at me like that before completely unprompted and unprovoked. such an odd thing to do.
