"When I was a cashier, I had a lady that came through my line that told me our prices were inconsistent because a certain drink was 5/$10 in one area and 2/$4 in another. She had like 20 drinks and wanted me to do a price check for the “real” price. After I explained to her that it was the same thing, she told me she was a teacher."
