I left my card in a news agents and did not use my wallet for 3 or 4 days. When I finally looked in my wallet, I went through the rigmarole of cancelling the card, etc. I then remembered when I last used it and returned to the shop. They had it, along with many others.
Got it back and cut it up.
Still, I have to look at my id card every morning, just to remind myself who I am
