I ate at Chick-Fil-A once sometime before it came to my knowledge that they were donating their money to evil causes (so pre-2011? IIRC) and honestly, not even their waffle fries were good. They were soggy and gross. Now, I'm sure they probably aren't always like that, but I simply don't care to try them again. They will never ever get a single penny of my money.
That deplorable franchise was even at both of the universities I have attended (the last one I lived at for two years) and even with the limited options (I can't drive, but could walk to the university easily) I still never had even the slightest bit of urge to go there. I really hope that whatever university I attend for grad school is above having such a bad place on campus.
Even if they turned around and stopped donating their money to evil causes, I still would probably never support them. Their reputation is stained beyond repair for me.
