The scene:
An adjacent Starbucks, the busiest one in the city, has closed that morning presumably due to COVID concerns. We're getting all their customers. It's Saturday, it's holiday season, and our team is four people. We've had to convert to drive-thru only.
Customer #1:
I hold out a drink to an old white man at my drive-thru window which is of course in a mug. I'm taking another customer's order at the same time. The man goes to grab the mug. I lower my arm so he'll grab the drink instead. He lowers his arm to go to grab the mug again. We do this a few times until he blurts out, "Give me my drink, goddamn it!" or some such. I say, "Don't take the mug, sir." What looks to be his granddaughter in the passenger's seat appears to tell him the same thing. He finally takes his drink, drives a bit forward, and makes sure I know how angry he is by turning back toward me and yelling, "FUCK!"
Customer #2:
One of our regulars, oddly enough another old white man, has previously spoken on the phone to our shift supervisor about what a shitty day we're having. He comes through the drive-thru simply to give us a $56 tip.
