A woman orders a chocolate milk. Then she orders a coffee milk (this is actually a regional thing where I'm from). Then she corrects me that she actually only ordered one drink: a chocolate coffee milk. My bullheaded coworker is very unhelpful in telling me that the customer said she wanted a "chocolate melt." I allow myself to get frustrated now, as the customer is not letting me ask questions and keeps saying her nonsense. "Are you new here?"

'No, ma'am. I've worked at Starbucks for two years. You don't know what the fuck you're talking about when you say you want a chocolate coffee milk. I rang you up for a misto with mocha sauce because a "coffee milk" is an actual thing in my region. Now please quit talking to your family about who knows what and complete your order and quit holding up my line.'

Reality:
"I AM new here." "That must be it then." "Yes, that must be it. \[coworker's name\], I've had enough of taking orders. Can I go wash dishes?" The woman complained when she got her drink because she wanted something other than a misto with mocha sauce, of course, and I didn't give one fuck to learn what the hell she wanted.
