(I’m working at the student dining hall on a busy Thanksgiving dinner as a supervisor. A student walks up with a glass of ice in hand.)

Customer: “Excuse me, but your Sierra Mist is out.”

Me: “Oh, no problem, ma’am. Let me go downstairs and I’ll take a look.”

(I walk downstairs and check the soda dispenser. The Sierra Mist is half-empty, but still functional. I tell her it should be fine. She comes back ten minutes later.)

Customer: “Excuse me, I asked you to fix the Sierra Mist and it is still not fixed.”

Me: “Ma’am, I just checked it and it’s full.”

Customer: “You’re lying. It isn’t working at all.”

(I walk over to the dispenser and place a cup underneath the Sierra Mist and out pours clear, bubbly Sierra Mist.)

Me: “See, ma’am? It’s just fine.”

Customer: “No! It’s clear! See? It’s clear! The bottle is green. Sierra Mist is green!”
