I'm a human and I'm not embarrassed of doing what every human does. I think farts are kind of funny too. I heard a dude moaning once, that was awkward but I just assumed he's gonna feel a lot better after everything is said and done.
The real issue is lack of privacy. Worst problem I ever had was a kid crawling under the stall at Red Robin and saying "dad", and I was like no bro, I don't think your dad is in here.
