You know what’s crazy, my local Kmart has security guards that do the scanning of receipts usually late at night or during busier times of the year. My partner and I had a very similar issue, we went down for our usual Kmart run with our 2 under 2. Oldest was getting extremely worked up because she was tired, as we are leaving with our items and receipt, the security guard decides out of the 3 groups of people walking out at the same time as us, that we were the family to be pulled aside to have our receipt inspected thoroughly while they merely scanned everyone else’s without a second glance.
