I don’t care if they do, frankly.
Restaurants already do this: Lunch is one price, Happy Hour another, Dinner another, and then late night often yet another menu.
A business can charge whatever they want, and hopefully it will empower more food coops and consumer owned businesses.
Edit: Most of the places I like to go to, I know who works there, I know who owns it.
I wonder if touristy places will eventually get facial recognition, so that prices are much higher for tourists?
Which leads me to the part that actually bothers me, the data collection and identification. Its not the pricing itself that bothers me, its the data required to do it.
