This morning, I was buying loratidine tablets at a chemist's where I don't usually go; I asked whether I could pay by EC card and they say yes, if I produced photo ID.
I had heard of this practice from customers_suck (often in the context of customers writing "see ID" in the signature line of their credit card and being indignant when asked to produce said ID), but hadn't encountered it in Germany yet.
Still, why not? I showed her my passport; she compared the names, then the signatures, between the EC card and the passport. I don't think she looked at the passport photo though or compared the signature on the receipt with the one on the card.
