How would a logo on the floor teach you to keep your head up?
Cause you're not supposed to walk on it. You know where it is right in the middle of the room. Though when I think about it more, I understand your question as you may be looking down to avoid the logo. I think we're getting away from the main point though, Bieber is a dumbass and he was likely told on the way in to Chicago don't step on the logo. I think Patrick Kane made reference on twitter or something too about someone stepping on the logo and called him a D-bag.
