If I'm the woman there, I will not allow myself to get expose myself with other people and will not wear a mask. Not weird but the face doesn't matter anymore.
Not maybe but they really are protecting their employees and the business too because one case can completely ruin their business and will go back to closing again.
I think that wearing a mask in a crowded environment like the Vegas casinos won’t really protect anyone if there are people with Covid in that environment.Studies have shown so far that if a person with Covid 19 stays for 15 minutes or more in the same office,apartment,shop or any other environment like a casino chances are high that other persons being present will be infected even if they are wearing masks.
If it won't protect anyone then why are people still wearing a mask and why the authorities are requiring us to wear mask?
Actually I haven't read about that study you mentioned, so if you are kind enough, can you please put some link on where do you read that?
In my opinion, it's better to do what the law says that is reasonable.
If wearing masks make people uncomfortable, they could avoid crowds, avoid coming close to people (assuming they can really do this) while moving outdoor "freely". Besides, such study has to be true and verified by most people (especially really qualified people) for it to change the current safety rules. Better to follow good rules until changed.
And like I stated before, you could still go outside mask-free (no mask covering your nose) without breaking the safety rules. But you'll need to have the mask on your hands just in case you need to go close to people or people are coming too close to you
