"Walking into a store can get you observed by stores b-z and subcontractior 1-255"

Well what about the new amazon retail store, that records your every move?

Also what about stores or shopping malls that contract their security cameras out to other companies? Surely those security companies may be doing all kinds of stuff with people's facial recognition data.

Most of the new data landscape is only adopted reluctantly - no shopper was given a choice in this. The fact that consumers feel powerless, and every medium to large business feels they must grab all the data possible, doesn't make it right.

Amazon's high street store is an easy to avoid aside until a Tesco or Walmart tries it.

I hope that GDPR restricts the extent of "all kinds of stuff" that companies wish to do to cctv security footage. I suspect it won't be nearly enough. The trouble with cctv is the consumer/shopper has effectively no way of knowing thus should be quite strictly regulated.
