To be honest I haven't noticed anyone behaving or chatting any differently now to what they did any other time. The only currency that that pound has dropped against is the dollar, but its all levelling out again, as it will, because in reality nothing at all has changed in the UK, the EU or anywhere else for that matter,
The Sterling/Euro is always up and down, but we don't notice it until we want to buy something. The dollar was $2 to the pound a few years ago, now its 75c to the pound. No one cared when it was $2 as everything was suddenly cheap, but now its the other way around, everybody cares, lol. If anyone is thinking of buying anything in $$'s from the UK just wait a while, the roller coaster will stop when the currency players have had their fun.
