in the UK they weigh the baggage area and if you don't scan something it'll shout "UNEXPECTED ITEM IN THE BAGGAGE AREA" as loud as the mf beep and you get publicly shamed by all the whiter than white old people.

anyone who puts bags outside the weighing area gets looked at too, there's no real way round without going for the old pockets

at the wm here, if you even look at the scanner cross-eyed, it sounds the alarms and halts the register until the babysitter can come over, review the footage and unlock it. if anything passes anywhere in the cameras' very wide fov and a scan isn't registered... anything... it stops.

they got sam's club-like checkers at the exits, now, too. anything not in a bag gets 'checked'.. at least that's what we've concluded is their criteria, based on when we have been stopped trying to leave.

me thinks they've had a slight uptick in 'customer-applied discounts' lately.
