Hey lady, why left your half eaten blueberries behind?

I know it’s not appropriate to take picture of her, but I just can’t help. Can’t believe what I just saw at Costco (7500 Pin Oak Dr, Niagara Falls, ON). She ate more than half of the blueberries and then tossed the leftovers on a random shelf and then left. she’s probably gonna eat something else next time. Blueberries are not that pricy though.
