Well...
Two things:
1. Unrealistic was, that the girl didn´t bleed! The guy punching her, had blood on his fist but there was nothing on her face. Even if her face was that hard, the guy should´ve mentioned it. So she lay on the floor and stood up like nothing was. In this time, the others could´ve stolen her bag-thing, if they really wanted to rob her. The joke about that "dumb girl who can´t read a map" was really stupid oO hm, what else...
2. The girl should´ve had bigger tits and blonde hair...would make the whole thing somewhat perfect ._.
