They knew the boundaries of what was acceptable I guess, and being "told off" really doesn't mean much to them. It did strike me as odd that none of the others called them out on it though.
But anyway, I can't see how it does them many favours. Surely if anyone is intimidated they'd not vote those pricks...well, one would hope. But like I say, the whole practice should be scrapped anyway. It's hard enough getting people to vote as it is, let alone feeling a potential gauntlet of eyes just to get in the place.
