Would I be happy? Certainly not!

Would I go through a crap load of trouble to sue a hotel chain for it? Hell no!!

And to be honest, if that is what your PA wrote, I would also not stand for it as a GM. You could have just written a letter asking for an apology without being condesending, even if you are a board member and all that.

If all those people around you agree the guy was out of bound, then how is this embarrassing to you? Nobody got hurt, everyone made their flight and the best way for you to make a point is by never going there again.

I wouldn't waste more time on it but then again, go wild if it makes you feel better!
