Analog film photography and cameras

Over here I don't bother asking. If it's abroad and particularly touristy I try to ask. Especially if it's obvious and that person (or people similar to them) have to endure us tourists constantly taking snaps of them. Feels a bit like taking photos of animals in a zoo otherwise.

CYOA - do you have teh fear of someone taking particular exception of them being photographed and demanded the entire roll?
Not second para so much, more the first bit.

I'm currently in indonesia and I don't want to appear like some kind of poverty tourist. But there are some very photogenic (totally inappropriate word) scenes here and I'd like to capture some, but don't want to come across:
