Few social environments are as cutthroat as a grocery store counter in the days before a holiday, when prime rib can turn otherwise reasonable adults into scheming opportunists. According to the post, the couple had missed the usual Fourth of July sale because money was tight. So naturally, they pounced when the store ran a second sale with prime rib marked down a whopping $6 per pound. The employee, per the post, quietly informed her that he had one more prime rib in the back. Few things unite the internet quite like watching a small act of unnecessary rudeness collect its bill in real time.
