The East Greenbush NY Walmart has their Greeters pulling double duty. They sit by the exit and as you leave the checkout, they stop you to check your receipt and cart.
They claim it's for anything that's not in a bag???? As it turns out most of their store's products do not fit in their grocery store sized bags. Due to their inept business practices, they embarrass everyone dumb enough to shop there. Any normal store will affix a "Paid For" sticker on such merchandise.
This type of paranoid behavior is at any normal retail establishment reserved for suspicious or real criminal activity.
Kudos to Walmart for making every customer feel like a thief. I now shop at Target which has the decency to have adept security guards doing their job watching cameras.
