Aggreed. It needs a bit of tuning. But I'm not sure that we are supposed to succeed...
I have the customers wait before I take their orders, and also before I serve them.
With this trick, you can maintain 6-7 customers. With luck, Karryn'll get drunk and boned before it goes to 8+
If she's a slut, you have to keep her pleasure meters low right from the start ny spamming the green skills every turn, and adjust her clothing if things get out of hand.
Still it's kinda fun when a brawl erupts all around a half-naked Karryn. It also seems like the angry customers won't start fighting right away, in particular if they are in range to molest her.
Also, it says that bar fights cost you money in damage, but I didn't notice it. Did I miss it ?
