I've had multiple accounts with McDonalds and over time, the discounts get worse and worse.
The hook you on the cheap Big Mac Meals, or $1 McFlurry, then over time they discover you actually enjoy Big Macs, so they give you less rewards for Big Macs, as you were likely gonna buy a Big Mac at full price anyways.
If you don't visit for a while, they'll notify you of a discount personalized to you, which is just on the edge of reasonable/worthwhile. You'll head to the store and spend money you would of otherwise not.
In the long run, the data tracking is designed to make you THINK you are saving money, but you are actually worse off! There is a grace period where rewards are good, you earn points and bonus points and you break even, but after a while it goes into a manipulative state to extract every cent from you.
