[Hitchhiker's Guide] What will 30 Altairian dollars a day buy me?

I figure I should know what kind of lifestyle I'm in for when I go hitchhiking with the guide in tow.

about half a sandwich in the average galactic spaceport, but with thirty dollars worth of materials available at most major interplanetary grocery outlets you can make *two* sandwiches.  From there you'll only need a towel to briefly commandeer an empty food stand at the spaceport, sell your to sandwiches and then buy standby tickets to whatever destination you could want!
