Went to top up on some groceries today (well £60 worth), and for the second time in a row, we had to re-scan the shopping. I actually felt like a criminal but can understand why they do it, just not why so often. We had had a few dodgy items which wouldn't scan, and we kept these out of the bags and told the cashier about them. I have to say it has put me right off!
Oh and why can't they let you know at the end, if there was a discrepancy?
Grrr
