My favorite was pretending to be a robot/prerecorded message. I'd put on my announcer voice to greet them, and then say "to place an order, press 1" but there was no keypad, so they would just say "uh...one?" And then I'd be like "para español, marque dos"

I would be super petty when Midwestern transplants would butcher the word "quesadilla" as "cassadila" by responding "sorry, a what? Oh, a quesadilla, okay" which got really funny (to me) when they would order several different kinds of quesadilla and I would do the same schtick every time within a span of 2 minutes

This was before I got woke, so sometimes I would put on an Indian accent and act like I was taking their order from an overseas call center

I used to fuck around in all sorts of ways there: putting a sign on the drive-thru menu telling people to yell bc the mic was damaged; not turning on the lights at night so people thought we were closed;

My favorite thing though was doing customer surveys (which would get printed and pinned in the back) and leaving insane reviews- like one went on and on about how the cashier was sooo hot, and then at the end mentioned he reminds me of my dad (that employee was a babyfaced teen which made it extra bizarre)
