Pass on a chair slam??

[Ebayref]

So at what point do we look the other way and let the head coach grab his metal folding chair and slam it back to the floor?
In a rec. game? AAU or even high school game? What if you're Roy Williams and the #3 seed and you're fighting for your
life late in the second half of round two of an NCAA tourney game? I think I know what I'd do regardless of the situation as
that is a very clear and distinguishable line that's been crossed. I'm guaranteed that all of my assignors (both high school
and college) would've backed me unequivocally if I had whacked him for the chair slamming. What are your thoughts?
