It the same logic as beggar .
When they are really poor , they only want food
When child is sick , they just need medicine
If they want $$$ , the something is wrong ,
If you break your arm , will you want ambulance immediately or you
want to borrow enough money just to make sure you are able to pay
up
Bring them to hospital , or buy them food , if they refuse , then
it $$ they want.
If they acept your help , they would rather want the ambulance than
paper money
And im sure local clinic some of the doctor are kind enough to give
lesser medication burden , unless they are those sort of business
doctor then i got nothing to say.
It possible coz i seen poor old man see doctor , really no money
type , the doctor give him free consultant and medication , and
encourage him to come back for checkup. This is what i call a
doctor.
Remember:
When someone is in distress , they will need help , much more than
$$
They will worry about the money in later stage
