Sweden's older population, the 70 plus crew, grew up in a Sweden without immigrants (besides the Italians that came during the 50's), black people, Muslims. No interaction at school, work, neighborhood lead to many of these senior citizens living in a Sweden that is today totally new to them. With people they know nothing of and have the utmost prejudice for.
Then came the Taxis. In most larger cities, a large number of immigrants or "new Swedes" drive these Taxis. And when you get old in Sweden and have trouble taking the bus or train yourself (especially while going grocery shopping), the government gives you a taxi card where you ride the cab for a small sum.
All of a sudden all these older people have to meet with Mamadou, Abdi, Nima and the likes. They sit together for a longer period of time and the final verdict on their OK'ness will be given in the end; whether or not Mamadou, Abdi or Nima, opened the door to the car and helped the passenger out, carried the groceries all the way to the door.
Like one older Swedish lady said: "I rode with a black fellow today. He was totally black. But he was soo nice to me, he even carried my groceries to the elevator."
