“…Ambiguities also characterized their relationship with clients: some experiences reported by the respondents denote a certain level of interpersonal recognition, while others reveal recurrent episodes of social humiliation, defined as a form of "suffering long endured and chronicled by people of the poorer classes … that, in the Brazilian case and several generations ago, was sparked by the spoliation and servitude that fell heavily on natives and Africans, and later on low-wage immigrants" (Gonçalves Filho, 2004, p. 22).
