Is it really that big of a payoff?
I’d like to say more, but I’m off to a McDonald’s for dinner. Good luck identifying me there, Ronald.

I haven’t touched McDonalds in at least a year.
There is only one I would go to that’s close to my parents house about 90 miles from me.
Maybe I’m missing something. But it takes McDonald’s a bit of time and money to compile such a dossier.

They only produced the dossier because he asked for it. Yes, there is a cost to collect and track the data, but it is mostly used to track trends and identify people to send marketing offers to.
My local gas station started a loyalty program that gave provide a $2.47 cup of coffee (after tax) for $1.07 if you joined and punched in your phone number on paying. I signed up and got an addtional 5 free coffees. I also get points, but I did not download the app to track that. I just want the $1.40 savings. After about a year of offering this they began requiring you purchase at least $3.49 worth of merchandise to get the the $1.40 savings. I stopped putting my number in as I am not ginving them the info, if I don’t get something for it. One of the clerks asks me everytime to put in my number. I made it clear to the regional manager that I was not happy with the change.
$2.47 for a cup of coffee is still cheaper than the Starbucks knockoffs that proliferate my neighborhood. The gas station is almost across the street from my home.
Not really. You scan the QR code, you fill out your survey, you pay with your phone, you use your "points". All results in a electronic data base built by you.
McDonalds is just collecting it.
And while the personal data is just something that they can sell to the data brokers the big money is in the meta data.
