they work. Just had the issue earlier in the week in the office. We participate in the local juvenile defender program as part of our pro bono. Had a young man accused of some pretty violent stuff and his family in who refused to follow our policy and mask up in the common areas. Told them they had to leave. Was called everything but a child of god by all of them including the R word. Told them they still needed to leave. My partner today got him a sweet heart deal avoiding placement which is where he should have gone. I just shake my head.
The point is I don’t know if they work or not. But on the off chance that they do, you need to wear one in here. It’s really that simple and anyone who refuses is a fool.
