This cartoon by Mac from The Daily Mail relates to David Cameron's admission that he had wined and diners wealthy individuals - who had between them donated millions of pounds at Downing Street and Chequers. A wealthy donor is seen leaving Number 10 Downing Street (the prime minister's residence). David Cameron, who is portrayed as a waiter discreetly angling for a tip, tells him, "That £250,000 was just for the meal, sir. Service wasn't included." If you look closely, you'll see on the menu that 'pudding is extra'.
