Its not just gay bars in California. My daughter said a pub in the UK scanned her driving license when checking her age. A supermarket chain just announced they are rolling out face recognition cameras. Its profitable and there will be endless "think of the children" type arguments in favour.

It’s probably inevitable in places like the US where in major cities tons of products are behind plexiglass due to “changing consumer habits”.

Those self checkout kiosks you see at places like McDonalds have facial recognition cameras behind the screen and they’ve been putting in facial recognition at drive thrus for targeted promotions tailored to each person.
