I can understand locking things up and requiring an employee to get it for you if they're experiencing theft. But I had a new experience at Walmart this week: they just physically barricaded the entire section so that no one could get into it. I needed something from there so I asked one of the employees if someone would possibly be able to get it for me, and was told no, the section was closed. (But it would reopen tomorrow morning, she said, when of course it's impossible for me to get there.)
I remember them blocking off part of the store at the beginning of Covid, when the government mandated that only essential items could be sold, so they restricted access to the parts of the store that sold non-essential items. But this is the first time I've seen them just shut down a whole department when their store was otherwise open. Even when they went through that phase when the pharmacy closed before the store did, they only locked up specific medications within the section; you could still access the section to get other things.
