How did they prove that’s where they caught it? Not saying you’re wrong just generally curious how it was positively determined it was caused via airflow at a restaurant from an asymptomatic diner. Seems there are a lot of variables there that could be misunderstood.I have yet to see any scientific reports that contradict the people who caught covid from eating in a restaurant were within the airflow of an asymptomatic diner. Also according to those reports, it didn’t matter how close you were, but rather it mattered if you were within the airflow.
Similar studies in offices, etc. again have not been contradicted.
