It's the impression that is superficial. The dutch guy obviously didn't have a real interaction with the egyptian man, so I get the feeling that the notion he gets that the man is "aggressive" stems more from a superficial reading of him based on prejudices he has for people of the arab community. Also, smoking hash is hardly drug abuse... The notion that hash is associated with people of lower class or aggressive behaviour is another superficial stereotype.
