Making money whatever happens
Due to the hurricane Sandy it wasn't possible getting to New York for 2 days. We were stuck in the airport waiting for a flight to New York. We contacted with the hotel to cancel 2 nights because it was impossible to fly!, and the hotel responded ok, that they gonna cancel the booking for that 2 nights. But when we arrive to the hotel they made us only a minimum "discount" for that 2 nights, we had to pay almost the whole price. 
The depart day, after the checking-out, we ask for a cab (there were no trains, no subway, nothing to go to the airport). They answer: "our private transport doesn't go, there's no gas in the city, walk to the 6th ave and do it yourselves!", and we had to walk looking for a cab in a city with no gas. Helping the costumers... always.
