I occasionally had disagreements with shop owners because I didn't have cash and I wanted them to add the payment fee manually so I could pay by card and actually - you know - buy stuff.

A lot simply wouldn't - like I was attempting fraud or something.

I once tried to buy a beer in a small corner shop. The beer was 2€. The minimum charge for card payments was 5€. I agreed to pay 5€. The shopkeeper refused to charge me 5€.

I walked out without my beer, sad, and wishing I'd remembered to carry some cash that day.

Couldn't you buy three? I mean, if you're already price insensitive to pay 5 euro for one...

I wish I'd thought of that at the time. I will remember that for future. Thanks!
