Blimey I'm glad it's not just me then. I recently withdrew £200 from the bank, went to do some shopping, realised I couldn't find the £200. Went back into the bank, asked them if anyone had handed in £200 as I had lost it (lost is is the key phrase!). There was much sympathy from the bank staff but no one had handed it in. After a further search of my bag I found the money in a secret pocket in my bag. By this time I was hot, panicky, my heart was beating so fast I thought I would faint. My DH always says to me 'every time we go out, you can't find your purse, phone, keys or something, Get a grip.'
I must try.
