Reggie Bush -- Shares the Wealth ... Cash Giveaway to Homeless People

Reggie Bush did an awesome thing in L.A. the other day ... he gave money to TWO people in need ... but we noticed, one of the beggars got WAY MORE than the other.

Bush -- who was cruisin' around town in his $300,000 Rolls-Royce Phantom -- pulled over for a male beggar and handed the guy a crisp $20.

A short time later, he saw another person with a sign ... and stopped to give her a couple bucks as well.

Nice work, Reg.
