the costs of a good meal

According to several sources, a certain billionaire, Roman Abramovich, spend a 47 000 USD for a lunch at a NY eatery
To his defense might i add that he shared the meal with 9 others and he left a 5 000 USD tip. He injected a couple of thousand dollar into the local economy and all he got was this cheap looking bill?
I'm disappointed. With this money they earned they could invest in a designer and a printing system to print out nice looking bills worthy of these sums of money...
