The underlying attitudes towards persons racially identifiable as "Asian" are expressed in, indirectly and sometimes directly, behaviors that express disdain and disrespect, especially, perhaps surprisingly, among lower socio-economic groups, including--and most virulently--other racial minorities.
Now that it is unacceptable to openly express reservations about African-American culture or to criticize individuals [a black person], without being very careful, it is still acceptable to treat poorly Asians and Asian-Americans. One of the reasons being the generalized passivity of the latter.
I have personally observed this kind of situation at the downtown YMCA, Seattle Public Library, in Section 8 housing, supermarkets (such as Metropolitan Market) or department stores (Target, Nordstrom, etc.). This may not happen all the time but often enough to make me wince...
Sometimes it is even Asians looking down or treating other Asians with disrespect or even contempt.
