(I am working a very busy drive-thru. A twenty-something-year-old woman has requested a very complicated ice cream order: a small milkshake, made with vanilla ice cream with caramel, hot fudge, peanuts, and Snickers on top, unblended, in a medium cup. It takes me a minute to figure out how to enter this into the computer. By the time the woman has paid, her ice cream has been made correctly, but in the normal small cup.)

Me: “I’m sorry, it looks like this has already been made in the small cup. Is that okay?”

Customer: “No, I specifically asked for a medium so it won’t spill.”

Me: “Well, I can put a lid on it. Will that work?”

Customer: “No, I have to eat it now. Can you just dump it into a medium cup?”

Me: “I can scrape it into a bigger cup, but the toppings won’t be on top anymore.”

Customer: “Why not?”

(Searching for something to satisfy her, I find a cup sleeve that adds extra room to the top and fits it into her ice cream cup.)

Customer: “Will it spill?”

Me: “Well, it’s a removable sleeve. But if you keep it in there, the ice cream won’t spill.”

Customer: “But I have to eat it right now. Are you sure it won’t spill?”

Me: “If you spill it, ma’am, it will spill.”
