What’s an example of skinny privilege you have seen?

Some overweight people (in most cases other women) giving unsolicited ‘compliments’ on my body (because I’m thin) and also go on to talk about their diet and exercise plans. I sincerely, loathe these type of questions because it’s like entitled and stupid on the part of people asking. Same with ‘pretty privilege’ and yet people are rewarded for this stuff, but would wilt in the opposite of fat or ugly whatever. Why not just drop this shit and people be nice to each other?
