I believe, due to a bug, the Bartender and Waiter in this Inn turn Hostile to you as soon as combat breaks out--no matter what your Reputation/Charisma is, no matter who attacked whom, as soon as weapons start flashing, the management hates your guts. So, as soon as combat starts, your guys whip out their bows and take aim at the nearest enemy--the Bartender.
You can either:
A) Not fight them,
B) Take the Rep. hit,
C) Don't use any sort of AI during this fight and micromanage everything, or
D) Charm the Waiter & Bartender, send them up to the front line, and let the bad guys kill 'em.
Guess which one I use?
