I worked at Starbucks. Does that count?
I had a local following. I was known as the Angry Barista.
River: Hi !!! Welcome to Starbucks. My name is River. Why are you here?
Customer: Uh, Uh, I'd like an Iced Carmel Macchiato.
River: Let me rephrase my question. What do you really want?
Customer: Uh, uh, uhhhh a Carmel Macchiato?
River: Would you like blood with that?
Customer: Can I get a black coffee to go?
