Hi, I do not know where else to ask this question - if this is in the wrong place then please do let me know where to post this. In January of this year - I was shopping out with friends, and used the self service checkouts, as I only had a few items. I had picked up several items, including one where the label has peeled off, and had stuck to the bottom of the smaller item below it. I scanned through all of the items, and was surprised that the bill came to less than what I was expecting: I ignored it, and thought I was quids in, and could't do maths.
