Interacting w/ Players - Best practices?

Any best practices regarding interacting with players? It seems like every time I attempt to do this, the player never takes it well. Is there anything in their player card which suggests whether someone should be treated tough or gently?
Secondly, are there any "tells" during the recruiting process that would give a glimpse into a player being a problem child or not? For example, when calling a player and the player not answering your question and sarcastically saying they fell asleep or playing a video game. Is that a "tell?"
