We have about 500 Euros in cash after a holiday (it's a returned deposit so there wasn't any easy way to use it up over there). While we normally keep amounts of up to a hundred or so for the next time this seems a bit much to keep in cash.
What's the best way of turning it back into sterling in our UK bank? We have a choice of HSBC, Nationwide or even possibly Abbey. My guess would be just to pay it over the counter at Nationwide but I'm willing to be told otherwise.
