At lunchtime I went to the cashpoint and withdrew £20, then went to Tesco and spent nearly £10. Tonight, coming home from my silver class, I decided I had a craving for rice pudding and tinned pineapple, so nipped into the corner shop at the end of Montagu Street. It's not my nearest corner shop and I bet I've only been in it about 5 times in 8 years, so it's not like they know me. I got two pots of rice pudding and a tin of pineapple and went to the till - only to find I had about 80p in change and no tenner. I said oh no, I'm sorry, I thought I had a tenner, I've no money, I'll put them back on the shelves, but he let me take them anyway and told me to bring the money next time I'm passing.
I found the tenner when I got home. I must have dropped it when I was rooting through my purse for bus fare.
