Talk:The Great Ping Pong Scam/@comment-1692500-20110816220007

I have a question: if the bill had always costed 700 dollars before and the caviar cost 600 dollars, that adds up to the price of 1300 dollars. However, if Tori tagged along for the first time, then wouldn't her meal have brought the cost up from 700 dollars, and Robbie's caviar would have been less than 600 dollars? Was that a mistake or am I just not understanding?
