well for me, i dun mind going a little of an extra mile (for a lot of things), to get a good photo.
helping to carry stuff, chatting, trying to build relationships, these are things that help people around you to relax and be natural. while its beyond my scope of just taking photos, its value adding to your work. what these helps is to get access and for people to not feel awkward around you.
just take a look at the documentary photographers. they are quite good at this sort of stuff, thats why they get a lot of the "moment" shots.
aiya put it this way. photographers are your best friends for that 5 minutes. after that you probably wont be seeing them again. so long as i can use it to my advantage, they call me xiao di, ah girl, i also dun care.
gu niang leh? hahahaha
