Without trust issues there would be no machine errors in my experience. Anytime there's an issue it's because I'm scanning too fast for the machine and it can't figure out how the weights work. Or I selected the wrong type of garlic and only the associate is allowed to remove items (why would you not let me remove items I personally added??).

Fair, the inability to remove your own items seems maybe a hang-up from an older view of privileged cashiers. The store I currently use doesn’t have weight checks except for weighed produce. You can leave your stuff in the cart and with the wireless scanner and a bit of forethought everything can stay in there. Different trust models makes things interesting. I have never been checked leaving the store and I don’t think social safety net or otherwise is the driving factor

Yeah, the not being able to remove items grinds my gears.

It's especially annoying when I am waving an item furiously, trying to get the poorly printed barcode to scan, and when it finally accepts it, it double scans the item.

Then when I have to stand there waiting for someone to remove the item is usually where I get disgusted with the process and give up on shopping, especially when it happens multiple times.

It’s definitely trust issues here in the Netherlands.

Buying something for under 5 euro bucks in a shop where middle school kids buy their lunches is almost guaranteed check. More than one in three times.

A different shop and a bigger amount — checks almost never
