Mary-Kate Olsen left a "wad of chewed gum" with the tip when she left a restaurant recently.

The 22-year-old actress dined with friends at New York's Bottino restaurant last week, but waiters were furious to discover someone in the party had left the used confectionery alongside their payment.
A source told the New York Post newspaper: "Mary-Kate was eating and drinking red wine with two guys at a front room table. At the end of the meal she pulled out a wad of cash to pay the bill and left a nice tip.
"But there also a wad of balled-up, chewed gum on the table. The waiter was annoyed."
This is not the first time Mary-Kate has been accused of anti-social behaviour. Last month, she and her twin Ashley were branded "disruptive, intrusive and totally disrespectful" by their New York neighbours.
The twins - who shot to fame when they starred on US TV show 'Full House' in 1987 - angered the West Village residents with their constant partying.
One resident said: "Mary-Kate and Ashley are two spoiled brats who change the character of the neighbourhood."
Another added: "It is a peaceful, quiet street. Plenty of other celebrities around this block - Sarah Jessica Parker, Liv Tyler, Gisele Bundchen and Julianne Moore - are good neighbours and blend in with the neighbourhood - but these two are invaders."
