I have stopped people from going into "hot" indoor ranges without hearing protection. This happened the very same day all the other safety laws were infracted upon as mentioned in the first posting.
I sincerely don't believe I will be attending that indoor range and will allow my membership to expire. It is not worth the effort.
Given your apparent stress over this stuff, I can see why. It is probably best for everyone that you do.
