KGBINC: Or you could do it for free... :)

Well, actually and regrettably, I can't. Unless, of course, the airline would transport me for free, the hotel would accomodate me for free, and someone would invite me for a free lunch.

However, as we all know, there is no such thing as free lunch. :-(

(Okay, there's still the option to eat someone else's lunch, but as far as I remember that's a different context. :-))
