this is by far the dumbest exchange i've ever had with a customer:
barista brat: "hi, what drink can i get for you today?"
idiot customer: "gimme one of those caramel (KARE-uh-mel) blended thingies."
bb: "sure, what size would you like that caramel (khar-mul) frappuccino?"
bb: "what size would you like?"
ic: "yeah, i heard you."
bb: "um, ok. did you want me to pick a size for you?"
ic: "you know, i don't appreciate you making fun of me."
bb: "i wasn't making fun of you."
ic: "well, you were making fun of the way i said 'caramel'."
bb: "no i didn't."
ic: "then why did you feel the need to correct my pronunciation?"
bb: "i never corrected your pronunciation."
ic: "yes you did! you said it like this - CARmel."
bb: "ma'am, that's how i say that word."
ic: "so! i say it like this - KARE-uh-mel."
ic: "i just came here to get a drink. i didn't think i'd be judged for how i say things."
bb: "believe me ma'am, i not judging you for that reason."
after her drink was made my fellow barista buddy put it on the hand-off counter for her.
barista buddy: "grande caramel frappuccino on the bar!"
idiot customer: "is that the same thing as a KARE-uh-mel frappuccino?"
barista rant: when it's closing time you have to leave the store, ok? don't sit there expecting to hang out all night. and when i walk over to where you're sitting and nicely inform you that it's ten minutes past closing, don't try and shoo me away because you're on the phone. guess what? your cell phone is portable - meaning you can still talk on it as you exit my store. don't huff and point to the phone attached to your head as if i'm supposed to slowly back away and leave you alone. if you don't want me to bug you during your phone calls then why don't you make them somewhere else.
