And they’d better check everyone, not just the likely suspects, because they’d be accused of profiling.
It appears to me they are checking in a non-profiling manner .... anyone with a large item that is not “baggable” is being checked, from what I can tell. I have seen plenty of older white men, retired types, getting asked to show a receipt. As I said, I keep mine out & if I have an unbagged item, I walk right up to them with the receipt ... one old guy “knows” me (we’ve had some interesting discussions when he’s on ‘greeter’ duty) & barely glances, pretty much just waves me on. Usually, I have bird seed, potting soil, stuff like that - cheaper at Walmart than anywhere else & saving money is a priority in these days of Bidenflation.
COSTCO DOES THAT.
