Scenario one: I am at home and the refugees are coming here. I will be polite, help where I can and offer assistance to the polite ones. Try and take something and Mr. Ruger will assist you in leaving my area.

Scenarion two: I am the refugee. I ask politely and offer to pay, say thank you, and don't take any more than what I need. Any assistance I can offer in the way of helping my benefactors is given.

It's all about being polite and not greedy. Expect nothing, be thankful for what you get and take no more than what you need.
