Pilot Program to Accommodate Muslim Cab Drivers in Minneapolis Airport CancelledUSA Today of October 10, 2006 had an article entitled "Cabbies, Culture Clash at Minn. Airport." The issue is that some Muslim cab drivers wanted to refuse service to customers carrying alchoholic beverages. If a cab driver refused to service a customer, he would return to the end of the line of cabs and would have to wait some time (up to three hours) for the next opportunity to take a passenger.
This reminded me of some pharmacists who resisted dispensing birth control pills.
The airport ground transportation had piloted a program where the driver could signal through a light that he would not take passengers carrying alchohol and then airport employees woud direct the passengers to a cab driver who would accept them, but the airport has cancelled the pilot program.
