Once, when I tried to purchase a locked item, it turned out they the buzzer thing by the lock didn’t even work — which the staff knew. There’s a local pharmacy half a block away. I’d rather patronize a store that doesn’t treat my attempt to spend money there as a favor they’re reluctantly performing

This. I’m pretty sure my local Walgreens doesn’t want people to shop there. It’s pretty much impossible to purchase any of the many locked up items.
