(I am working alone in a very crowded kiosk. A customer points at a soda refrigerator.)

Customer: “Can you tell me which ones do and don’t have gas in them?”

Me: “Gas?”

Customer: “Yes, gas! I want one without gas!

Me: “Oh, okay I think you mean carbona—”

Customer: “I mean gas! I don’t like it.”

Me: “Well I’m sorry to tell you this, but everything else except for regular spring water has ‘gas’ in them.”

(The customer keeps staring at the refrigerator quietly, then picks up one soda.)

Customer: “Does this one have gas in it?”

Me: “Yes.”

Customer: “How about this one?”

Me: “Yes.”

Customer: “Hmmm. How about this one?”

Me: “Yes. As I said, only spring water doesn’t contain any gas. All the others do.”

Customer: “Well, I think I’ll take this one anyway and try out for myself.”

Me: “Okay, great, that’ll do two euros.”

(After about 10 minutes, the customer comes back.)

Customer: “MISS! IT DOES HAVE GAS IN IT!”
