Asking about "Friday" instead of the date would've sufficed.
A Zales in Omaha, Nebraska, decided to have a sale on the one day a year you can't have a sale and then promote it with the worst sign in history. This is some next level tastelessness. I'm surprised they didn't offer wine tasting flights along with the question "ask us about flight 93!" or maybe "sales so hot they'll melt steel."
The store manager told the NY Daily News that the promotion was a corporate idea. Who knows how high this thing goes; the diamond industry is already full of shadowy international business practices. The bad news for Zales is that just like diamonds, the internet is forever.
