A skeptic is someone who questions what they are seeing, and uses their intelligence to try and deduce an explanation of what they are seeing in an attempt to better understand the world around them.
A hard spectator, may be a skeptic, but generally is not. They are just people who A) don't really want you to be there right then, B) Is not having a good time, C) is just a generally cold person.
A heckler, is someone who tries and deduce a method, fictional or not, for malicious intent. They usually want to draw attention away from the performer and try and gain status in the social interaction. They should only be ignored until the appropriate moment for you to leave, rears it's head. If the heckler wants to be the funny guy, the ashat, you as a perform, paid or otherwise, should not attempt to offend or embarrass that person. You are only yielding to the alpha and giving that person reason to not like you more.
