From what I remember of "Young Zaphod Plays it Safe", Zaphod has some sort of regular job, and he doesn't do something horribly foolish when he could.
Zaphod's running a used ballpoint pen business when a "perfectly safe" ship crashes next to his underwater shop. Then something escapes from the ship and heads towards the area where earth is and the men who come to look at the ship say that area need to be made "perfectly safe". I still don't quite understand it all.
I am relatively sure that he is running a salvage buisness, NOT a pen buisness.
