Much amusement amongst the Irish contingent at The Gathering this year; one of the traders was over from Germany and hadn't converted Euro prices to UK - I don't think they'd realised beforehand that the UK doesn't use Euros. None of the UK attendees could figure out whether their prices were good value or not... (They were! *And* they took Euros from those of us who had them and GBP from everyone else. And yes, they did spend the first day frantically rewriting price tags.)
