Cash Back Attack, Part 3

(It is common practice that you can ask for cash in shops when paying by debit card.)

Cashier: “That is [amount].”

Me: “That ‘ll be debit. Oh, and can I have 20 euros, please?”

Cashier: “I’m sorry, ma’am, we are not allowed to give cash. Only the service-desk can.”

Me: *I shrug and on a very neutral tone* “Okay.”

Cashier: *suddenly aggressive* “Well, don’t blame me. It is store policy. Nothing I can do about it.”
