Removing the weight verification would make me reconsider self-checkout machines. There are other stores that I frequent where the weight verification is off, but my grocery store seems to be the only one to keep it enabled.
The part that grinds my gears is if I don’t allow the machine to verify the weight and scan the next item, I have to sit through the entire TTS message that explains what I’m doing wrong before I can correct my mistake and move on.
Any time I’m buying more than 3 items, I typically just go straight to a human-operated register.
The grocery store near me has the most annoying security feature on their self-checkout machines. After you scan your item, it must be placed on the checkout shelf before you can do anything else. If the weight is “unexpected”, you’re stuck asking for help. If you have a full cart of items, you can’t parallelize tasks because of this deadlock; the machine refuses to scan the next item until your current purchase is on the checkout shelf and verified.
Would either Calckey or Misskey be a good fit for what you’re looking for?
