When I went to Tesco yesterday to get my weekly groceries, which I pay for with my debit card, I also drew out £100 in £20 notes from their cash machine as I like to have a bit of cash, in case it is needed during the week. It was only when I got home I noticed on one of the notes someone has scrawled upside down in ink on frontside of it the numbers 1350, how weird??? I have put the note aside and will take it with me when I go the supermarket next week and show it to the manager to see if he has an explanation.
