(A customer approaches the concessions counter.)

Customer: “Can I have a diet soda?”

Me: “Sorry, the fountain here is all out of diet soda.”

Customer: “That’s fine, I’ll just have a regular soda then.”

(I give her the regular soda that she asked for. I then watch as she goes to the condiment table and grabs about 5-6 packets of artificial sweetener, dumping it all into her drink.)

Me: “Um…? What are you doing?”

Customer: “I’m making it a diet soda.”
