Hustlers: no thanks and keep it moving beach hustlers usually have their territory and won't cross too far into the next.

Vendors: not thanks and keep it moving if I see something I like, I'll make an offer and be quick to walk away if it's not accepted

Truly hungry women/elderly folks: if I have the resources I will purchase some box food for them; never cash. have been known to pick up some rice and things at the grocery store. I don't buy booze or cigarettes for anyone.

If I'm in the mood to give a small blessing to someone, I'll look to the one in the corner off to the side who doesn't ask and discreetly give. sometimes those folks get preyed upon if someone sees they've gotten something.
