Most players expect their fellow players to be helpful, working together as a team to accomplish any tricky tasks that need to be done in the game.
If you introduce a player relatively new to roleplaying to the game, make sure they understand this. Or all sorts of terrible things can happen.
GM: What kind of character do you want to play, Sally?
Sally: Someone smart! And sensible. And not stupid looking.

Obi-Wan: Thank you for letting me into the Jedi Archives, Miss... that's you, Sally. You're a librarian.
Librarian: Miss Jocasta Nu!
Obi-Wan: Thank you, Miss Nu. I owe you one.
GM: Right. Sally, you're a keen assistant who craves advent—
Librarian: I'm a little old lady with long robes! And chopsticks in my hair!

Obi-Wan: I need—
Librarian: Hey! Quiet back there! This is a library, you know!!
Librarian: Sorry, go on.
Obi-Wan: I'm trying to locate a plan—
Librarian: Oy! You lot! No eating in the library! Do I come around to your house and read books?!
Obi-Wan: —et called Kamino.
Librarian: Tough luck! All the books about planets were eaten by dogs.
Librarian: Also, you don't have a library card any more 'cause you're suspended. So get lost!
GM: Mmmm. Well handled.
