Floyd Mayweather -- 6 BODYGUARDS ... For Chicken & Waffles Run

He's the best fighter in the world -- by far -- but Floyd Mayweather still invests in protection ... bringing SIX huge dudes to watch his back at one of the most famous chicken joints in the world.

Floyd and his posse hit up Roscoe's Chicken and Waffles in L.A. on Friday -- and on the way out, Money hid behind his wall of muscles as he and his lady friend made their way to a waiting SUV.
