A person who talks down to people, who thinks they are superior to everyone else. They are very condescending in nature. In other words a complete bitch or asshole.
A patronizer will say things like "Stop that or I will make you go sit in the corner" or "That's a conversation for outside of this office". They will say things like this and use a patronizing or condescending tone of voice.
