((You're at NoleRads, the newest fast food joint in the area. You're waiting politely in line, when you see a woman yelling at a worker because her giftcard didn't work. Her name is Karen, and well, it fits.))

She's yelling at this poor young cashier.

"You obviously weren't trained for this. Get me a new worker, this gift card WILL work!" she demands, slamming her fist down on the countertop.
