I agree, and I'm really against data surveillance. The data collected in this example is exactly what I'd expect, and frankly McDonalds should have the right to collect this. If you go to a local store all the time the owner will get to know your habits, this really isn't any different.

The red lines here would be adjusting pricing for an individual based on this dossier. Also, correlating this with data obtained from elsewhere would be really bad. Sharing this data with other parties would be really bad.

I think that would be the real story here. Is this data sold to 3rd party aggregators?
