I did qualify my comments with the 'if' word. Too many times in my career I have seen drunks on board who got thru just because the boarding agents wanted to get the show on the road. Off-loads mean bags have to be found in the bottom of the cargo hold and cause delays. And I have had cabin crew ply the punters with p!ss then come bleating when someone plays grab-ass, or suggests a game of hide-the-sausage.
