What time you usually cook, so the best time to show you other advertisements

I guess I can grant you that they would learn that I eat dinner around dinner time, maybe a little later than most but also not abnormally so.

or if you’re in the store once super targeted customer by customer pricing gets implemented (it’s already in place in many locations)

I’ve seen that stores want to be able to adjust prices based on time of day or whatever, and my store has mostly switched to eink price labels so it’s a matter of time… But per person? How are they supposed to offer one price to me and another to someone reaching for the gallon of milk at the same time?
