1,300% profit

Met a friend tonight who had good news. He had just made 1,300% profit on a deal and pocketed loads of cash. So happy for him. He said dinner was on him. Which was all nice and dandy until the restaurant rejected his credit card and it turned out he had 10 CHF in cash. Guess who had to pay? But seriously, I'm extremely happy for him and wish him all the success. PS. He did pay me back so no worries.
