Even if a store does have a sign, I still don’t wear one. Very seldom does an employee say anything.
Dallas county stores have militant true believers. If I see people walking towards the door without a mask, I let them know they might get yelled at. Everytime I have been right.
I go to the Junkyards in Dallas county, because they have parts for the cars I need, and even in the toxically masculin junkyard, there are pussy mask nazi’s.
Tarrant county (about 50/50 Trump) is way more relaxed about masks.
