It actually happened to me once, when I was in London dining in a restaurant. I wanted to pay in cash that I withdrew in Scotland and the lady did decline the money I gave her. Pretty wild for me as a German doing a little trip through the UK.

> I wanted to pay in cash... me as a German

Very German thing to do, yet in the UK I have not had a need to pay in cash, just use your card (or phone/watch if you are into that). Dunno if it was the money type, or just not want to be dealing with cash per se.

No, that'd never happen, but only because there's no such thing as a single pound note any more.

A wonder if a pound note actually meant a single pound (or just pound type, e.g. £5). It's a genuine question how it would be perceived in the UK, esp. when spoken by non Brit/Irish person.
