Facebook marketplace primarily for anyone I know that still uses it. Also people having messenger as their sms app and not knowing the difference or using their Facebook account to sign into every other website and games. Don't forget every Instagram and WhatsApp user is pressured to link their accounts too. Meta makes parasites seem friendly and helpful 🙃
Plot twist: Russia deploys an army of roombas to collect them.
Because that's double handling and the scales where I shop have bag holders on the side of the scales for their own bags, hence they are designed to account for the bags weight before scanning and placing items.
The self checkouts where I am get confused from things as simple as a customer placing their own bags on the scale before even scanning anything and constantly need staff intervention. Not to mention how often prices are wrong on these systems. For the cost of constantly developing, upgrading and maintaining them. In the long run companies would be better off training a few extra staff for express lanes instead. Only my humble opinion though.
Self checkout is a corporate excuse to not train employees and instead get customers to work for free performing point of sale. Expecting customers to be trustworthy and care about performing this task competently for free is "fucking dense".
