Black Friday Was (And Is) Banned in Certain Places
There are still places that will not allow them on certain days. For example, though some shoppers would want to start their shopping for the holidays the Thursday night of Thanksgiving, Maine, Massachusetts, and Rhode Island all have laws banning people from working on Thanksgiving Day.
