Facial recognition systems are everywhere, even in Poland small shops(FreshMarket, etc.) have it built into cash registers. Is this something that concerns me?

Facial recognition systems are everywhere, even in Poland small shops(FreshMarket, etc.) have it built into cash registers. Is this something that concerns me? Absolutely not and I can even say I don't give a fuck. Most of the government institutions already have your photo, signature, and many more from ID/Passport or any other government documents you made. So why you should be afraid of companies who does it too? I know, I know, privacy, ads, tracking and stuff. :) But is this still fight for privacy? I see many startups us this rhetoric to acquire clients. But it turns into a terrible joke like it was with usability 15 years ago. Where companies offered services that were not needed to collect even more money.
