Busho just keeps telling me to stop bothering him or it will just take longer to finish the job.
I have left and reentered town, stayed at the inn, talked with many merchants, and he still hasn't finished the windows.
What am I missing?

This is my last quest in Fay before leaving town and I think I have to go outside to work in the yard until someone can help me.

EDIT:
okay, I left the town again and fought 2 groups of orcs in the "wilderness" around town and returned to the pub. The windows looked fixed but Busho still has more work to do. I guess a couple more battles should do it. This is a game where you should really pay attention to what is said. We know Indi can be a bit devious, but he's buried valuable clues in the conversations and I have just barely touched the beginning of the game. I like good stories, so I don't usually "fast forward" through the speech, but I apparently missed this Orc clue.
