If you are a pilot, candy bars, porn and free beer are the very essence in life. Candy bars, because that's all there is at the airport at 11:30PM, Porn, because you are away from your significant other for 300+ hours a month, and free beer, because it allows you to forget the miserable life choice you made years ago and being drunk evens out all the above.
There!
Nice. I'll agree on the porn and beer, but I'd rather get the cheese and crackers from the vending machine than the candy bar. Neither is a desirable choice which is why I have a couple of protein/granola bars in the front pocket of my suitcase. They're always smashed up but if I'm that hungry, I don't mind.
