Was it wrong for me to tell these people to wear a mask?
I was at the gym and a family was going around to tour the gym. They were not even exercising, and were not even wearing a mask. I told them "you have to wear a mask here" and one of them snapped at me and told me "those people on the treadmill are not wearing a mask."
If you don't wear a mask in a mask mandated business sometimes people will tell you to wear a mask, but most of the times they won't. That said, they should be prepared for rude stares or people telling them to mask up. Its that simple.
