Usually a lot of faces give the crowds high fives and what not. But i'm wondering that does Vince or many other managers tell them to do so or is it from their own choices? Because every time I see a face ignore the kids reaching their hands out kind of makes me wonder about it a bit more.
I think its more about superstars just doing it if they want to. They can't shake every hand around them, so they would have to "ignore" some fans at times because they can't get to everyone, only a few while the star walks down the ramp
It's mostly midcard faces that slap hands with ringside fans and it's usually part of their entrance. The likes of Cena and Orton never do it unless it's a 'special' (like Cena announcing Bin Laden has died and celebrating with fans). Same with the top faces of the past such as Stone Cold and The Rock.
