I get it. I occasionally find situations where I have no viable option as well but we stand and fight the battle we can win and the enemy does the same.I wish I could do this for everywhere I go (though most places are fine with me not wearing one).
Unfortunately, there's at least one place I've been to where the receiving desk absolutely refuses to even talk to anyone who doesn't have a mask on, and will refuse to unload my truck until I come back with a mask, despite the plexiglass window between me and them and the fact that they're already wearing a mask.
So I put a dirty one on whenever I go there, if nothing else, so that I can at least get in and out of there as quickly as possible, and it only goes on while I'm inside the doorway, and comes off immediately after I leave the desk.
The fact is that the left has very nearly won and it's gotten to the point now where the exercising of our freedom puts our livelihood at risk and we have to make decisions about which battles are worth fighting. The left will continue to win too. The only thing that can stop them now is a civil war, which they stupidly want and think they would win, by the way.
