[Hobbit: An unexpected journey] Gandalf and the dwarves are overall courteous and nice people. Yet at beginning of the movie they are uncharacteristically rude.

Gandalf self invited himself and 13 dwarves to someone’s house who straight up refused. After coming to his house, they throw his food around, treat it like their own house, treat him like a butler by thrusting their weapons and coats on Bilbo. Sure by the end of the journey he got repaid for it many times over but they weren’t sure that he’ll accept the invite to the journey from before. What made the dwarves and Gandalf especially act so uncharacteristically?

Gandalf will do whatever it takes to get this quest rolling. Much like his fellow Istari, including those two blue brothers, he’s on a mission from God 

The dwarfs are demonstrating that manners can vary by culture. They were led to believe he was a host and that he respected the rite of sacred hospitality. They also didn’t break anything and even cleaned everything afterwards.
