The masks are if you want to go into mass transit or peoples’ businesses, and it’s mostly theater in restaurants - they come off and stay off almost immediately. It’s just common courtesy to others to wear them in public places while omicron is raging.

The QR code scanning is just for dining at the place (not takeout), and for things like long trains and planes. It’s not a big deal, except for the privacy implications.

My point was mostly that people aren’t holding back from going out, despite very high infection rates, and things appear to be mostly fine.
