Never mind Lewin, I just tested it and you are right. They will stop as soon as I close the inn. Surely they will bring in the food if they were already on their way, but that's okay with me. I was thinking that they would bring more food even after I closed the inn (thus ignoring what I did), but that's not the case.
Closing your inns is brilliant, thanks Dark Lord
I know it is, you're welcome.

I figured it takes too much time to provide the inn with food when you have like four serfs, so a long time ago I came up with this and it works perfectly. You can now build your school faster, train more serfs, and open the inn again (preferably when they have nothing to do of course).
