Doesnt surprise me, have seen videos of people shoplifting right in the open and staff just stand there, including security. Just walking into store, emptying a self then walking out.
Opposite to what I see in America where you get manhandled instead.
Self checkouts must be having people doing fraud, its just too tempting for human nature.
The policies generally are observe, record, keep customers and colleagues safe - more and more retailers are rolling out body worn cameras though in an instance of shoplifting that does have the potential to escalate a situation if staff enable their camera especially if lower intelligence shoplifters don't realise they are live streamed.
