I think the fatter out-of-shape women who place themselves next to the fit women do so in order to seem more "fit" by association, like "hey everyone, check it out, I'm next to this fit woman working out and I'm working out too! See how we're the same!?" And ewwwwwww on the creep factor, I hope you reported the ham that took a photo of you (even if it was a suspicion), that shit is definitely not okay.
