I agree with you, and think it’s kind of obvious, which is why nobody is testing for that I think.

If you spend long enough in a small room, even with someone wearing a mask the mask is not going to do much to prevent transmission.

I think that’s why the first rule of COVID is to not stay together in small rooms.

The important part is if you’ll be instantly infected by someone talking with you over the counter for a minute, and for that scenario masks are (apparently) pretty great.

The only way would be to wear N95+ masks yourself.

And properly. Almost no one wears one properly, because it requires training, correct sizing and e.g. to be shaved. Mandating that everyone wears masks without training people is lunacy. When they inevitably don't work people lose faith is science because they were told there was scientific evidence that they will help, when in fact scientific studies were made only in specific, limited conditions.
