This is why I OC where I can. Especially out in the general public. I also try to acknowledge everyone and smile. I dress nice and try to generally be helpful. I put shopping carts away for people. I offer to lend a hand loading cars. I go out of my way to pick up litter. I ask people how they are doing and engage where I can.
It's a pain in the keister because I am normally an introvert. But it is important to put a good face on carrying and help people understand we are not slobbering nut jobs.
If a place posts 07 I conceal and proceed. If they post 06 I turn around and go someplace else. I wont go into Sprouts because they are posted 06 and 07. My wife goes in while I wait in the car. I would much rather go to Trader Joe's. They started out posted 06 and 07. They have finally removed to 06 signs.
