Three years ago I went to the post office in a big city in France, there I received change back after I paid for something. I didn't look at it first but later on I discovered that I received a €5 coin. EUROS not francs.
Two years later in a medium city in Germany I went into a shop to buy food. There I gave money to pay for my food including the €5 coin. The shop assistant looked at it then said:
We only accept euros here…
I answered: it is euros look closer
He answered after looking again: sorry we don't accept such payments
I found this on the web in French
Can I pay with a €5 coin? Or is it only for collections? Was the shop assistant doing the right or the wrong thing?
