I will not give money to homeless people.
Need food? Follow me to the nearby McDonald's and I'll buy you a sandwich.
Need gas? I'll swipe my credit card and may even help fill your tank.
Juggling blades/fire, playing some music, or otherwise making things interesting on the street? I'll leave you a tip.
Otherwise, don't bother asking for money while you hold your latest model iPhone or drive your BMW. I live on a college campus too; why are you asking us for money? We're probably just as poor as you.
