I'm sure we've all done this.
I went to the cashpoint, put the card in, entered the appropriate PIN, selected the option to withdraw cash, took my card out again - and clean forgot to pick up the money. I just walked away, head in the clouds.
Five minutes later, I realised my error and hurtled back to the hole-in-the-wall where, naturally, someone had collected my twenty quid.
Good for them. Nobody was about and it was their great good luck. I had to withdraw another score from the machine, feeling decidedly irritated by my absent-mindedness. I'd had a busy day and there is much going through my mind right now.
Like I say, I'm sure we've all done this...
