I just saw a guy shove loads of chocolate bars and candy into a big black bag, get two beers. I got curious cause usually people don’t put stuff they intend to buy into bags.
Then he proceeds to checkout but only pays for the beers, not a single beep from the sensors. Are they only meant to detect certain items or did the homeless guy have something to disrupt the sensors?

Are you sure he didn’t scan them before putting them into the bag?
At my grocery store, [you get a scanner gun when you walk in](https://i.ytimg.com/vi/kv1RgyrO558/hqdefault.jpg). There’s a little holster for it on your cart.
You pick a can of soup off the shelf, scan it, toss it in the cart.
Then at the end you just put the scanner gun into a holster at the self-checkout, and it knows what you bought, and you put your credit card in to pay, and you walk out.
You don’t have to take everything out of your cart to be scanned.
