Is quid really used in UK by 80-90% people? I thought it's very informal slang word (of some lower educated people), in China most of the people just use kuai (well I guess not bank tellers).
Pretty much everyone uses it in informal settings in my experience.
In a professional environment, people usually say pound.
The distinction is context-based, not class- or education-based.
It's my understanding the same is the case for kuai vs yuan as well?

I deal with Brits on a daily basis.
I seldom hear them use the term "pound". Everyone says quid.
