It happens to everyone sooner or later. You get to work with the nagging feeling that you are missing something. Something important, all the way until you pull in to the car park at work.

And realise you have forgotten your wallet.

I have a supply of coffee at my desk, no problem. But lunch may be a problem unless...

15 minutes later after heading off on my break, I have a pound coin in my hand scavenged from my car ashtray. Will it be enough? Where can I get something decent for only a pound? Prices have risen, I doubt I'll get a sandwich for that much. Can't even buy 2 chocolate bars at 70p each round here.

Lady luck smiles though, as I chow down on a small sushi box for only a quid. Exact money, how's that for luck?
