I think some here forget that Beyonce was at her work-place. The guy should have thrown into the street as a message. Besides its common decency to not grope a passing female celebrity at a concert. Now Bret Michaels at a Poison concert walking through the crowd of gobsmacked girls/cougars...? He's knowing things are gonna happen what with kisses and squeezes on his butt/junk. Damned man-whore!
If I were to pat any of our female employees on their butt, no matter how lightly, I'd be up for all kinds of sanctions and civil liability.
