The perpetual victim class who, in reality, tends mostly to victimize others.
It never seems to occur to them that Caucasians, Hispanics, Asians, et al. receive bad or indifferent service too. Just read a random selection of restaurant reviews on Yelp and you are sure to see complaints about bad, rude, hostile, indifferent service received by members of EVERY group. Most people will give a place a few tries, and if service is consistently bad, they stop patronizing that place and go elsewhere.
So true
