Honestly, unless there person doing it is the owner it is probably because the employee is sick of hearing about it because they can't do anything.

A district manager noticed they were being displayed backwards. The deli manager went to a training class and fixed something they were doing wrong. A new deli manager transferred from another store and trained her new people to do the job correctly. A new deli backup went to train in a different location and learned something they were doing wrong. A different assistant manager was put in charge of deli and corrected the behavior. They were hosting a district meeting and when all the district leadership came to help prep the store, they were retrained.

These are all real life scenarios that happen in real grocery stores. I'm pretty confident that the shitty scale label was never meant to be facing forward, regardless of the price. If they are "hiding" the price, then why are they not hiding the 50 price tags in the service case over at the deli counter where they sliced it in the first place?
