Reminds me of the Kingston Trio song M.T.A. about a dude stuck on the Boston subway forever because they raised the fare from 5 to 10 cents and he couldn't afford to get off. His wife handed him a sandwich every day through the window so he wouldn't starve to death. As a kid I was like "bitch, why not put a fucking dime in the sandwich?"
According to google, a sandwich in 1949 (when the original song was written) cost 4 cents. Three days trapped on a subway and you've already made a colossal financial mistake.
