In parts of the US, even low-crime areas, a significant amount of the items at grocery stores are locked up in glass cases. If you want them you have to track down an employee and beg for access (and in some stores they won't let you carry the items to the register). That part of the store might as well be closed to visitors, replaced by vending machines.
Hah. In my Safeway, the ice cream and half the frozen aisles have a lock on every door. I can’t imagine how much inconvenience that causes everybody. The employees openly say it’s ridiculous and you regularly find a queue in each aisle waiting to be individually served by an employee with a key unlocking and re locking each door they want something from.
I won't buy this stuff on principle. Microcenter locking up the 5090s is one thing, Target locking up a $15 pack of socks is another.
