I would have a conversation with the owner. If he wasn't there then the employees may be doing this without his knowledge or consent.
If he has any sense and he didn't know he should poop red building blocks upon hearing the news, as I doubt his business liability insurance will cover that level of stupidity.
This is what I was waiting to hear. I will pull him aside next time I am in there. If one of my employees was doing something questionable I would want to know.
There are things we strive to do to garner credibility. Then there are space cadet things we do to lose credibility. Then there is just the absolute height of irresponsibility with a total disregard for personal safety and bordering on criminal.
