Hammerbarn is go
I'm a bit biased here having had a son working in retail who was abused and told to F off when he asked the customer to pay for the stuff loaded in their trolley.
Based on the video shown on the news last night in relation to this story (various scum attacking staff and customers), I feel that Bunnings Duty of care to their customers and staff overrides any qualms I have about my face being recognised. I think the area they fell down on was not having signs up saying that you agree to be filmed on entering the premises. Having setup up surveilance systems for a number of clients, I'm sure that having FR would be a boon as in most security systems, the video is stored and re-visited after the event.
If this prevents someone with a known proclivity for theft and violence from entering a store, myself as a customer welcome it. It saves me money ( not having to pay more to allow for "leakage") and prevents me being placed in a situation where I may be injured.
