The term comes not from some politically incorrect reference, but has acquired a double meaning over the years. Some believe it is derived from the fact that it is still well before dawn on the Friday after Thanksgiving when some stores open way before their normally scheduled hours in hopes of acquiring extra revenue from holiday shoppers. Others believe the designation is because this is the one day that is a guaranteed success for retailers. A chance to be "in the black", or profitable, from an accounting perspective.
Some stores are advertising that they will be open as early as 4 a.m., with potential customers already camped out on their doorsteps in hopes of getting some good bargains.
Yet those people are standing outside braving the late night/pre-dawn weather voluntarily. Imagine what time the employees scheduled to open that morning have to be there!
In any event, I wish those either brave or foolhardy enough to venture out the best of luck, but please remember to be polite to each other. There were some bad incidents reported last year concerning the abundance of customers versus the limited quantities of selected items at various retail locations.
As for myself, I will be warm and snug in my bed fast asleep.
I'll leave it up to you, the reader, to decide who is following the wiser course of action.
