My question if you have the same contact and the opposite persons keeps on giving contacts and you keep on saying I have the same one then what is the logic behind this iteration process ???
Another thing not everyone will say I will give only when you give, some may want to know what options you have, it doesn't mean he is not willing to share.
Next question if people are not obliged to try out an Indie, why do they ask in first case??
There is a difference between exchange only in return of exchange and a person trying to know what all you have so that he doesn't give you that only.
If you say I don't have any what's the harm,?? we are ready to share in that case also. Don't judge everyone by same aspect, that's what I am trying to say
