Well, at least you know now that those people have NO morals. Hopefully, you can avoid them, I sure would.
They're out there for sure. I have a customer who just told me on Friday that her daughter's best friends family all went to France recently....they all got covid while there and yet...they when the positive tests returned....the father of the family pushed two hundred euro notes forward....and the family of four all got negative results uploaded to their phones. My customer wanted me to be sure to know that the family of four "triple masked" on the way home. I thought, yeah...ok, I'm sure they did. So, that kind of stuff has been happening for sure. Now that there's no testing, it will continue to happen, but some of those people won't even bother to wear masks. So...travel at your own risk, wear a KN95 minimum....N95 if you can't take it....and you'll probably be okay.
And if you're wearing a KN95 like I see most people wearing them....you're not doing it right. Go to You Tube and watch a video about how to properly wear one.
