Actually no, my card was declined. I had a problem with it in the village shop over the weekend, but so did lots of others as the card machine in there is a sort of dial up thing, and the connection was playing up. They did mention that it seemed to be mainly Nat west cards.
Soooo, today I go to Waitrose, went to pay, card declined. Left my shopping there while I went into the bank to ask what the hell was going on. Turns out the Mr P had been late transferring from the business account to the private one and there were "insufficient funds" 
So, back to Waitrose to explain, had to ask them to take the shopping back (thank god it was only a packet of tagliatelle and some cilit bang and a few other random items)
Came home, phoned Mr P (NB I didn't shout, so extra points there I think) checked both accounts, the money had left the business one but hadn't landed in the private one. Must have been floating about in the ether somewhere.
