There are a lot of strange issues that simply don't let that happen.

1. He normally carries no food, but when it's time to eat it suddenly spawns in his inventory.

2. Sometimes he will just take a seat and do... nothing. No eating, no drinking, just sitting there.

3. Sometimes he stops to talk to every random npc during meal time.

I've been struggling with this for a whole, hellish hour.

And no, I won't kill him another way. This is how I want it.
