Why would a man check you out from head to toe constantly when he sees her but he isn't interested enough to approach her?

Why would he otherwise check her out from head to toe constantly?
Not attracted or not interested enough? Not his type but likes the view but don't want to start something?

It's like he is hypnotize when he checks me out constantly. He didn't see that I noticed it. Why would he keep looking at me like that (eyes and mouth wide open)? It always goes like that.
