Interacting with monks in Thailand

I'm planning to visit Thailand, so I would like to know some simple local "rules" to interact with monks respecting Theravada tradition, I want to avoid behaving like a tourist that (not intentionaly) breaks the protocols, also I want to maximize the experience there, so I will list some specific topics: - How to approach to do dana? Can I offer to buy food for them or should I just give the food? - How to interact in temples or centres, can a lay person start a conversation or would it be distracting therefore not a good idea? - Should one bend or prostate to the monks? Or make the gesture with the hands (similar to praying)? In what occasions? - Any specific advise for women when interacting with Bikkhus? Not touching them? I assume they should avoid some revealing clothes as well. - Any other specific advise? Many thanks!
