Assuming that the man who writes Spybot and distributes it world-wide is sophisticated enough to travel short distances, then if he goes to Scotland, has an employee who goes to Scotland, or has a little niece in Scotland who is having a birthday, then would the bank note still be useful currency? (I have seen references to currency changes in the U.K. in recent decades, and I have no idea how many years this note has been in our house.)
Guest, there is no question of going to a bank and exchanging the note. By the time the fees were deducted, there would be nothing left.
Auldtimer, it shouldn't be called a DEEP SEA DIVER, it should be called a WEE TIM'ROUS BEASTIE.
