I once bought laundry detergent at Walmart and was surprised to find it locked up. Had to buzz an associate to open the case and then take it to a register so I could purchase it. They wouldn’t even let me carry it to a register myself.
The irritating part: directly across the street was a Sam’s Club (which is a Walmart company) and they don’t lock up detergent. Just stamps, high priced electronics, and high priced alcohol.
I chuckled.
