Earlier quoted context omitted.
In basically every retail store, and especially grocery/convenience stores, you are being observed by security cameras at literally every second. In every aisle. This has been the case for decades. It's how they catch shoplifters. I rather like the fact it can be used for customer convenience now, rather than just punitively.
The constant filming from every angle is what makes me even more confused when you need to personally tell employees that something is broken somewhere, or the queue for the cash register is miles long, or some sales point isn't staffed and has people waiting. Everything is being watched, why aren't they reacting proactively?
If you want to see a shopkeeper care about that sort of thing, patronize an owner-operated small business.
