I've gone to Hardee's for breakfast a couple times in the last year. It's not the cleanest, but it is really good in the morning, though I've never seen a woman there and I do feel disgusting afterwards. Considering I only eat fast food on the rarest of occassions I don't feel too bad about it.
Not sure why a woman wouldn't go to Hardee's. There are just many overweight grease-eating women as there are men, at least here in BNA-land.
