Apparently manners is not one of Angel's strong suits:

Typical Criss Angel antics. No....He has NO manners, whatsoever. His mother needs to be seriously b*tch slapped for not teaching him any.

The Angel-hate is getting a little pathetic. If his girl's sick, they shouldn't be in the audience. If it's a bad show, they shouldn't be in the audience. If he's decided he's going to be a douche, he shouldn't be in the audience. The fact that he got up and left is something we'd commend bad spectators for doing during our shows. Maybe he just wasn't feeling it that night. Remember, Berry did call him out in the middle of a show, which is pretty messed up.

This one is a bit silly, you're right. They are feuding about it on Magic Café as well, which I got sucked into darn it!

I said this on Magic Café and I will echo it here - Now that he is dating Hef’s leftovers, more gossip columnists will be noting every non-newsworthy moment until this gal, (Holly), comes to her senses and moves on.

I will also add something which another poster said so nicely,
I really need to stop feeding into the Criss Angel gossip; it’s becoming a bad habit for me…
