McDonald’s Offers Toy Exchange: McDonald’s Corp. is warning customers that a toy car offered in a promotional campaign may pose a choking hazard for young children. No youngsters have been injured by the futuristic Doc DeLorean cars, McDonald’s said. But as a precaution, the fast-food giant is allowing concerned parents to exchange the miniature car for another toy offered in the “Back to the Future” Happy Meal promotion at no extra cost. “Some small children have been able to remove the rear tires with their teeth,” a McDonald’s spokeswoman said.
