I did hear a rumour that he donates to organisations with an anti-gay agenda. How true that is, I don't know.
This is my cousin's reason for no longer spending her money at Chick-fil-a. I have not put in the effort to confirm it yet, as I don't eat fast food very often anymore anyway, but if I locate confirmation I will stop spending my money there as well.
Frankly I feel sorry for anyone who works in a fast food joint period.
Actually, as far as fast food places go, Chick-fil-a is one of the best ones to work at. They take good care of their employees and even offer a scholarship program. I enjoyed my employment there.
