Hi Dris. Hope you get it back. A coach driver friend of ours left his at a motorway services recently. He didn't realise until he got back home, and gave them a ring. Yes - they'd found it for him amazingly, and they even posted it on to save him trawling all the way back there to pick it up again.
Strange you should lose it at the same time as I lost my doorkeys today!! Searched my bags and the car - nothing there. Went back to the supermarket car park - and there they lay, despite another car being in the space by then!!
