Many people cannot be vaccinated against covid, i.e., if they have allergies, and plus the person must be healthy, i.e., as well as from the flu vaccine. There should not even be a small hole or caries in the tooth. We just don't know about it. And at the school of the Olympic reserves, they do not vaccinate even for the slightest deviation of the body, even a small hole in the tooth is an obstacle to vaccination. So draw conclusions
The service is good and necessary. But can this service somehow motivate sellers and cashiers to get vaccinated against covid? Otherwise, it turns out to be absurd, unvaccinated sellers force vaccinated buyers to wear masks. The question about vaccination is answered, no, and we are not going to. How is it? Then let them sit in masks themselves, otherwise they are not going to, you see, but everyone is suffering.
I demand from the SES to introduce travel in elevators for one person if possible. Since the elevator has a closed volume of < 2m3. When traveling, people are forced to breathe common air, with virtually no ventilation and natural air exchange. The available ventos are made with dimensions according to safety requirements (so that not a single finger gets through).
There is no need to come up with a better place to transmit infections.
