I just walked into a Wal Mart Neighborhood Market that requires masks, without a mask, and the person at the entrance said I need to have a mask and tried to hand me one out of her box of masks, and I just ignored her and kept walking. Was able to get what I needed without a mask and wasn't kicked out or anything.
No idea why people at this point STILL believe masks work or make any difference.
At mine, they take your temp in the lobby and ask a bunch of questions about your health before you can see the doctor, and they give you a sticker to show you've been approved. But neither person doing it was really into it and you could tell they didn't care.
