I have 2 Royal bank of Scotland £10 notes. For some reaosn no shops in Fareham, Portsmouth, Gosport or surrounding area will accept them. I've never had a problem in Devon, or Cornwall or Kent or nay onther areas of Southern England.
Anyway I'd enough of having £20 in mypusre that I can't spend so went into a bank today and asked if they could give me 2 English £10 notes in exchange and the response was "we don't change money, foreign or otherwise".
They were taking the piss surely?
