Was This Victoria's Secret Model REALLY Fat Shaming People?

A lot of people felt like Victoria's Secret model Kelly Gale was mocking and fat-shaming people outside of an In-N-Out Burger by refusing to eat their food and working out by the front door.

I really can't figure out how I feel about this...I can see where people would feel like she's fat-shaming, but as long as she's not in peoples' faces ridiculing them for their food choices, who cares WTF she does?
