A matter of word choice

From a customer today who was looking to find individual servings of iced tea, but found only our quart and gallon sizes:

Flustered tea-drinker: "I looked over by the tea and I only saw the big jugs you guys have. That's it? No smaller sizes?"

Me: "Yes. That's it...just the big jugs."

FTD: "Yeah, I don't really need the big jugs right now."

Me: "Fair enough. Sorry to disappoint."
