Stop shopping at those places? But... if you have stuff from them delivered, should you turn the tables and have your own face recog stuff turned on them?

You're not turning the tables on them, you're turning the tables on the random gig economy worker who got assigned your delivery. It's not like the CEO of the pharmacy chain is delivering your case of red bull or something.

Ideas to tackle it:

Wear your covid mask, sunglasses and sunhat everywhere. Also put heel inserts in your shoes to change your height/walking gait. Or just go full privacy burka with a headshape altering chef's hat or mitznefet.

if you do that everywhere, they'll still be able to find you, via your new pseudo-identity

Put a bag over the camera before beginning your transaction!

I was somewhat hoping full face mask/helmet wearing would become in vogue in the past two years with all of the masking requirements like we see in so many sci-fi shows and movies. Algorithms would move to gate analysis or other things, but at least facial recognition could be crossed off.

If a air born pandemic can’t move society in that direction, I fear that we’ll never get to our perpetually masked future.

You planning on sneaking up on the camera from behind?
