Baht Nothing

(I am at a cafe at the departure lounge of the airport, queueing up behind some tourists heading home. Note: All the notes and coins are clearly marked.)

Tourist: “How much is this bottled water?”

Cashier: “It’s [amount], ma’am.”

Tourist: *shoving some change at the cashier* “Here.”

Cashier: “So sorry, but you are short by [amount].”

Tourist: *gives a note* “Fine. Here. I don’t understand your currency. I want my change in [Home Country’s currency].”

Cashier: “I’m sorry; I can only give you change in Thai Baht.”

Tourist: “This is outrageous! What kind of place is this that you can’t give me change in [Home Country’s currency]?!”
