One Hot Coffee Equals Three Cold Ones

(We are on a business trip. It has been a long drive and we stop for something to eat.)

Customer: “Can I get a coffee, please?”

Cashier: “Sure; it will be just a moment.” *to me* “How can I help you?”

Me: “Hi, three [meals], please.”

(The cashier sorts a tray out, and starts loading up the three soft drinks for my order. At this point the customer before me wanders off and comes back with a straw, picks up one of my drinks.)

Me: “Er, excuse me, what do you think you’re doing?”

Customer: “What?”

Me: “That is obviously my order; you ordered coffee.”

Customer: “Oh, I, err.”

(By this point his coffee is finished.)

Cashier: “Your drink, sir.”

Customer: “Yes, err, thanks.” *scurries off*

Cashier: *to me* “Did he not notice there were three of them?!”

Me: “How did he not notice it was ice cold?!”
