I drove a cab, and the behavior of these drivers in Minnesota is contrary to the entire cab business.
Half the trips out there are picking up or driving patrons to bars and homosexual hangouts, hauling Mr. Lush and his 2 cases of beer from the local beer distributor to his home for a weekend of serious drinking, transporting the blind with their guide dogs or transporting people with their pitbulls.
I don't see how these muslim drivers make any money, their business model seems defective. Being liberal (in the traditional sense) in what one will accept is essential in that business.
