In the Chilly D's "fat girls" controversy, is it the problem that the girls are fat (I assume that they actually are), or that someone recognized that they were fat and wrote it down. Or perhaps both?

Or to put it another way, is it likely the girls do not like being fat, so they hope everyone else will not make note of it. What if the guy in question noticed, but simply did not write it down. And why is it national news? If I get shitty treatment at a restaurant, I just don’t go there anymore.
It’s sort of a psychological question, I think.
