you just exhibited the fallacy of equating a restaurant to a beach (or being outside). You are also using "exposure" in the most generic sense of "presence" within a distance. That's really not how it works.

Like I said there is absolutely no evidence that you could get infected while in an open environment, moreover plenty of evidence that being outside is greatly beneficial to health and well being.

Now I am asking you the same question you asked me: "why would a bureaucrat want to go out of their way to close a beach if there wasn't a good reason?"

The answer is simple as unpleasant, they don't understand what they are doing.
