Maybe due to the German fondness for cash?

A few percent higher prices aren't as much of a deal when paying with credit card, the transaction works exactly the same, but when paying cash, it might look very different (up to "don't actually have enough with me. oops.")

This stands to reason, credit card use in the UK is very high. So high in fact I recall several times before I had a chip card having trouble paying at cashless kiosks.
