Got home from shopping yesterday and needed to add the cost of some items that I had picked up for my sister. One of which was a litre of milk. It was tesco finest channel islands whole milk. I picked it because it was 5p cheaper than the Cravendale. £1.25. But looking down the list about 3 times, it is not there. So I got myself, or my sister, a free bottle of milk. Every little helps.
In case you are wondering I had paid at a normal checkout. I hadn't accidently not self scanned the milk.
I told this to my friend in The Gambia. She said I should either take the milk back because it's not mine, or go to the shop to explain and offer them the money.
