Stereotyped as a crook

I own a construction company.  I’ve worked very hard at building a good reputation.  I’ve gone to people’s houses to give a quote on a job, and been greeted with a frown.  Then followed with a statement that asks if I’m from another Black community that has gotten a bad rap for cutting corners and taking money. (Even if it’s a sterotype)  I have to defend that I’m not from that community, even though I have friends from there because they won’t give me the job.  The first thing out of their mouth is: “are you from _______?”   I never win a bid with the corporate industry, or city bids. It’s always the same companies.
