Larry,
You're right, of course. Just a bit of irony on my part. In England, unlike Scotland, we gave up £1 notes years ago, to be replaced by £1 coins. It always feels as though I'm carrying a pocketful of shrapnel!
To set the record straight, there is no problem in getting Scottish bank notes accepted anywhere in the UK. Now it's different with Irish £'s or Channel Islands coins, but that's another story.
Incidentally 2 banks in Scotland issue notes. 'Bank of Scotland 'and 'Royal Bank of Scotland'. Look out for them next time you're this side of the pond!
