Mookie Betts Serves Food At Raising Cane's For Charity, Hundreds Show Up

Before Mookie Betts steps up to the dish for the Dodgers for their home opener, he was out serving dishes at Raising Cane's ... doling out a bunch of chicken and fries to a grip of fans who turned out to support him.

The shortstop worked a shift at the fast food chain's location in Alhambra, Calif. some 24 hours before L.A. takes on the Cardinals at Dodger Stadium in order to raise some funds for his foundation ... and hundreds flocked to the eatery to get a glimpse of the baseball star.

Mookie was in great spirits as he worked the cash register ... handing out tendies and Texas Toast with a big smile on his face.

Betts also signed autographs for those who ordered from him -- before he addressed the massive crowd that showed up.

The 31-year-old thanked everybody -- and then he received a $100,000 donation from Cane's for his charity.

Amid all of the festivities, Betts spoke with TMZ Sports about getting behind the counter ... saying he was sure his many times as a drive-thru customer would translate to the other side of the window.
