Upper class people don't bother with it because we all know those discounts are temporary but they'll never let go of the data they extract from those apps and will try to spam you
One can always use a fake email and login account. Upper class people don't bother because they don't eat at fast food chains as often enough as lower class people to warrant needing an app for each one; 99.9% don't give a shit about data collection, only people on HN and other technical fora do.
>One can always use a fake email and login account.
When you're using that fake email be sure to have a burner phone or public internet so they can't link it to your IP, also don't use your computer or any computer you've logged in on so that browser fingerprinting doesn't tag you, also turn off your GPS so they can't geo correlate you.
Of course the rich person is in the same boat, their geolocation will log that they went to Burger King, or their credit card company will snitch on them. Okay, fine, pay with cash, cover your phone in a tin foil faraday cage. Now you also will need to drive a 30 year old car to said establishment since the car manufacturer put a cellular modem and GPS in your car and sells the fact that you went to Burger King to the highest bidder.
That's all I can think of off the top of my head, I'm sure there are dozens of other ways people are tagged. At some level may as well either use the app or just not go.
