No, no, you’re mathing correct. I did receive 12ct back. But 12cts is a 2ct coin + a 10ct coin. If I would have given 51.00€, it would have been a 2ct coin + a 5ct coin back. I didn’t mention the 2ct coin, because it’s always involved.
And I didn’t have 3cts myself, otherwise I would have made it 51.03€, yeah.
Honestly, I have no idea, if the cashiers are allowed to take extra change here, at least in the supermarkets.
I still want to try that at the town market, where I’ve always been too stupid to think of that so far, so I once got told that I could’ve kept that 1ct coin and one time, the guy actually gave me extra change, because he did not want to deal with those small coins. 🥴
