Floyd Mayweather gives $300 tip to every cook at Catch Las Vegas

It’s not uncommon to hear about celebs leaving big tips, but this is a new one.

We hear Floyd “Money” Mayweather went to Catch Las Vegas with 16 friends for a pal’s birthday, and after dinner, he visited the kitchen and gave $300 to every cook.

“He personally thanked everyone,” said an insider. “The cooks were ecstatic and thankful!”

Perhaps he’s trying to rehab his tipping rep in Sin City. In 2014, a waitress claimed the champ had run up a $25,000 tab at the Hard Rock on an order of 200 chicken wings and 20 bottles of Champagne — and didn’t leave a cent.

A Hard Rock rep later denied the story.
