I was annoyed that on trying to top up my oyster card in the local newsagents (I won't say where) they wouldn't accept my Scottish ?10! I explained to the young man, who managed to temporarily stop his phone conversation (that also annoys me but it's another thread), it is legal tender but he said "my boss won't allow it!" Another customer asked me if I was using a euro note! A EURO NOTE!!! I explained it was not foreign money but sterling! Anyway, his boss wasn't there and I had a train to catch so I paid by card! Imagine the uproar if the Scottish refused to accept English money?!
