How is the captain pi@#ing away money???

The meals are already loaded, no extra FA's needed?? Explain this to me? If the F class meals are short - so be it - I'm sure the 3 the captain upgraded would care less on NOT getting an F meal (assuming DEN-IAH had a meal?)

Would you have been happy if the captain hunted around the terminal looking for proper people to fly (e.g. NRSA's??)
