Mariah Carey
The Queen of Christmas left employees of one Atlantic City eatery less than cheery this week, when her team reportedly left a zero-dollar tip on the star's $500 meal. A source told Page Six that "Chef Will Savarese [of Robert's Steakhouse] prepared the meal with extra attention to make sure that everything was perfect for the notoriously finicky pop star" and when a staffer picked up the order, they paid $500 for the $493.67 bill and asked for the $6.33 change back, leaving nothing.
