I've NIP'd pretty much everywhere. If we've been there, I've probably nursed a baby there.
With this baby, the most notable NIP experiences would probably be when DD was in the hospital. Whenever they would need to draw blood, change her IV, etc, they would offer "sugar water for the pain." I would instead just pull out a boob and lean over the exam table and nurse DD through the procedure with my boob dangling down. Some of the nurses thought it was "sweet," one commented that she'd never had a mom do that (but wished more would because it made things "so much easier"). All of the doctors except for one seemed very uncomfortable, and one of them even commented that "I'm sure you'd be more comfortable nursing privately." I just smiled and told him that if I could nurse in Starbucks every morning, then I could certainly nurse in front of a pediatrician
A friend had posted a link on FB (probably one of you ladies) about how we learn to nurse by watching. Our brains have some innate ability, yes, but that the knowlege of how to nurse is actually a learned behavior, and that a big part of that is seeing. And that by hiding in private rooms, under covers, and behind closed doors, we are doing a great disservice to future nursing generations.
I think the only person I'm not comfortable nursing around is my dad, because he makes it so awkward. He won't look at me, he turns away, he tries not to talk to me... It makes me super uncomfortable. He's gotten better about it, but probably only because I'm on my second child that nurses all the time...
