I get a kick out of giving Northern Ireland notes to businesses over in England and watching them squirm about. You can see serious confusion as they look back and forth between the words "Pounds Sterling" and "Ireland". There's a look of "If i get a manager I'm going to look stupid, but if I don't, I might be in trouble for taking fake money". There is a large number of people in London that aren't quit convinced that Northern Ireland is part of the UK.
