What does chez Pilot Books mean?

Means you be there.

You know, from that description - particularly that line about "... and the occasional sales transaction." - it sounds like you're paying to run the cash register. Seriously. The title of the resulting compilation is "FINANCIALS?"

I couldn't find any more information on their website, it looks like this was just an email. PR stunt?

Ahh - "receives a stipend." As the nice lady with the crazy hair would say "nevermind."

But it still sounds like you're working the till.

Oh, you are. But there's not much till to work :)
