Taverns are free to play, yes.

And, if you'd had the Moff in there prior to my character walking out of the backroom and THEN you'd done it? I wouldn't have worried.

But having a character pop into a thread he wasn't in for the sole purpose of chastising one of my characters? In a fashion that could be taken as an assault on my play-style?

Well, sorry, but it appears like you were just trying to piss me off.
