Valet -- LeBron's Mom HUMILIATED Me!

LeBron James' mother screamed the words, "Don't you know who I am?!" -- before slapping a parking valet this morning in Miami ... so says the "humiliated" valet himself.

Rockfeller Sorel surfaced in Miami earlier today -- where he told reporters he feels completely humiliated -- and vows to take legal action against the NBA star's mother, Gloria James ... saying, "I need justice."
