they probably won't.I suppose so. Not many people are going to put up with the hassle of being overcharged 10 cents (25% over display price) on cup of soup, but the store knows you would notice a 25% markup on a $500 TV scanning in at $625. To them, it's a 25% increase in profits either way. But keeping it on the lower priced items is easier for them to get away with it.
You know darn well that if they found an item scanning in a lower price than the display price, they would have that corrected immediately!
Many years ago the big store in town would offer gas at a rather low price and have the penny fraction (I am sure there is a name for it) at 0.5 cents (it was pfennig at the time, in Germany) per liter.
Easy enough to absorb it by adding a penny to the high volume items.
I noticed that as of late the customer display at Walmart does not work.
So you are practically guessing if the stuff rang up right.
A lesson from my dad, over 40 years ago: check the receipt before you leave.
Alas, as to the service issue.
I am glad I have not run into any of those folks.
I tend to be the sympathetic ear, learning as I listen, (now I think I need to find a new GP, as they don't pay staff and have nobody working there anymore)
I have gotten a steep discount on my son's haircut because I patiently waited for the lady to have a smoke after the shop schedule had blown up in her face (the beauty shops at Walmart have crazy rules, y'all!)
The paint mixer in every store I have ever been to was splattered with paint.
I think it's a given. eventually, a can will blow up.
I am generally in the (lucky) position to brag on the folks I came across.
phew.
I think we are experiencing a historical moment though.
Corporations are (slowly) learning that they have to pay to retain good staff.
