The current cashier’s need to start making mistakes such as all merchandise 10 cents.
Whole Foods employees had some latitude to offer reduced price or comped merchandise.
I’ve seen it happen in the hot food area (comped slices near the end of day) as well as in the meat market (have a complimentary or price reduced link of a new seasoned sausage). In neither instance was the discount requested or expected, the items were ordered and the staff took it upon themselves to make pen notations on the pricing sticker.
Software keeps an eye out for just such a thing. All grocery store chains have that.......................
