This has happened before. All of this may happen again.

Came back from excellent gig by The Eden House; casually browse my bank accounts on line and check a pre-paid  cashplus card I keep for buying extra trinkets and stuff  of that sort (I don't have or want a credit card, I got badly stung with those), in which I had a hundred quid. Had. There appear a number of transactions in places I've never been, for the sum total of every penny there was in it. Now I have to go through the hassle of trying to sort that out. Bah. Shame, it'd been an excellent evening. thus far.
