Here is my take...if someone is asking questions even though they could research on their own, I'm happy to help as long as they are willing to learn. Would it be better if they figured everything out before they got the snake? Sure, but I figure it is too late now, and telling them off isn't going to help anything. Ultimately the snake will suffer. Some of the people I have helped with basic questions have turned into customers, too, so I imagine the help was appreciated.

On the other hand, if the person has an attitude, then, there is only so much you can do.
