Handwavium is right. This is how it works in France. See if you can grasp the logic.
You need vaccine and booster to get a health pass. Or a negative test from the past 3 days. They are going to take away the test and recovery options this week though, and make it strictly a vaccine pass.
Packed onto a bus or metro with 50 other people? No pass needed.
Waiting in a lunch line 5 cm apart? Even inside? Fine without a pass (because you are ordering carry out). You can even find police in these lines. It's fine apparently.
Crowded outdoor market or crowded supermarket aisles? No pass needed.
Sitting down at a restaurant eating? BANNED unless you have a pass.
Standing at the bar eating or drinking? BANNED for everyone, even if you do have a pass (seriously, it's specifically forbidden to eat standing up. You can only eat sitting down).
Sitting down at restaurant eating "outside" (including sheltered terraces that are 90% enclosed? Fine without a pass.
The health pass is seriously a joke they invented just to punish unvaccinated people by banning them from doing fun things, with absolutely no connection to spreading the virus or not. But they are just doubling down and blaming unvaccinated people for everything.
