There's a reason why "contestants hug and kiss him all the time on his show," according to Tommy Greco, co-owner of K Rico Steakhouse in Manhattan.
After Carey left, Greco turned to his waiter and told him "Man, what a really nice guy." And according to Greco, "my waiter goes 'No kidding—look!' and he showed me the tip."
On a bill of $200, Carey tipped $500, a 250% gratuity, which was split amongst the entire restaurant staff.
Greco said, "You always hear about people being jerks or doing the wrong thing, but he's an amazing guy — super nice."
