And if you use cash to buy alcohol? But this is something to talk to a lawyer about if it mean that much to you.

well, this is in Denmark so

1. hardly anyone uses cash, although sure it is possible, but then my bank transactions would show I never take out cash.

2. Sure I will probably also talk to a lawyer, but you don't really get any payment for your time, so probably what I will instead do is to make complaints to various government agencies, and to do that I want as much data as possible.
