Gas station bathroom poop

I avoid public bathrooms all I can. But for convenience when I'm on a long drive I stop to pee at when I fill the thank.
(But I think I'll start to pull over on the side of the road to pee all the time now)
So I was wondering, what does those people that poop in gas station restrooms and leave it there for everyone to see, what do they eat?
