As far as I'm aware, facial recognition works mostly by measuring distances between identifiable features of a person's face, like eyes, nose, mouth, face outline, etc. Hiding major facial features behind a mask that covers your nose, mouth and jaw can definitely confound at least some facial recognition systems. Wearing a mask and dark sunglasses is better, though some systems can penetrate through dark lenses (there are special sunglasses built to prevent this).

Sunnies, a hat and pay cash.

Just effectively they have monopolised, have unfair trading practices with small businesses that supply goods, are increasingly changing product for their own brand which then means the "lowest price guaranteed" is pretty null and void because you can't buy their items anywhere else.

Just noting, I watched this a long time ago, but it left a bad enough taste in my mouth to stop me from going there any more

I now just go to the specialist stores. Some times might be a bit more money, but often much better service.

• Go to mitre 10 / dahlsens for generalist store (or if you're lucky you might have a small family business) -Total tools / Sydney tools for tools
• Reece for plumbing goods -Local wood provider for wood. -Metal land for any metal needs etc. Sure, strictly speaking it's not as convenient.. but good service, good quality (variable) , not supporting a Monopoly. -----------

Buying Online, and some other small hardware stores still around. If you are building anything bigger, specialized retailers will give you much better price.
