May Be Switzerland But Her Feelings Are Not Neutral

I work at a gas station in Switzerland, right at the border with Germany. An older German lady comes into the store and wants to pay for her gas. In Switzerland, you pay after you fill your tank.

She throws all these coins on the counter.

Customer: “I’ve been on holiday in Switzerland, and this is the rest of my money. I’ve exactly filled my tank so that I can spend all of it.”

Because we have a five-cent discount per litre today, she actually gets 2.10 in Swiss Francs in change. I explain this to her.

Customer: *Angry* “I counted it exactly! You must be wrong!”

After multiple attempts at explaining:

Me: “See this as a gift from the company! You could spend the money on something else?

I refer to our selection of chocolate which is quite popular with German tourists. She just gets angrier and angrier.

Customer: “I do not want to buy any of your stupid chocolate!”

I then politely informed her about our tip box. She ended up throwing her remaining money in the trashcan.
