@sbi Funny how UPS and FedEx don't seem to have an issue with where the package label is on the box. Either their setup scans the entire thing to find the label, or there's stages before that where it flips the package/box so that the label is facing the correct way. I do make it a point to run over any old labels on boxes (when reusing them) to make sure they don't get scanned. At the very least obscure enough of the barcode that it's not usable. IF I print out my own label, I make sure to cover up any old labels too.
Really does seem like a pretty major failure on the part of the system the USPS is using. Be that from the provider, or how they have it set up. I wouldn't be surprised if the maker of the system offered additional options that would have eliminated these issues. But the people making the decisions (at the USPS) decided to not get them (for whatever 'cost savings' that brough about). Never mind how the customer satisfaction levels keep going down year after year.
Hell, not even related to any packages. Half the time (if not more) when I go out to my mailbox, the damned lid isn't closed. Not sure if the person doing the route just doesn't give a F, or what. Or if they slam it so hard that it flips back open. Then they can't take the extra two seconds to just close it. Especially annoying when we have wet weather and things get soaked due to them.
