Yes? I don't particularly care whether or not the grocery store knows exactly which products I buy, especially since it's moot with 1) the introduction of eye-level facial recognition cameras at every checkout lane and 2) paying with a card because I don't want to carry cash.
Which country is that? US? I am glad in my country we do not have eye-level facial recognition cameras (I'd assume that would be illegal), and I can and happily do pay with cash.
Yes, the US. Virtually every large chain is doing it, even in the relatively remote area I live in. There's really no such thing as privacy here, too much money to be made tracking and selling to people.
