Glory Hole battle scenario:
You can deduct from the code in the newest available version that glory hole battle should combine bar and receptionist job when it comes to mechanics:
1) there's a guest satisfaction that is increased if the guest is receiving the type of sex he prefers
2) satisfaction is lowered if Karryn performs a different type of action that he wants or if the glory hole is occupied and he has to wait
3) if guest's satisfaction is >0 there's a chance glory hole reputation will go up. If <0 there's a chance it gets lowered. If the wait is longer, Karryn's pleasure damage against this guest is lowered.
Probably the challenge/tricky part would be to provide pleasure for the glory hole participants so that the most are satisfied in the quickest way.
4) Apart from two glory holes there's mention of the urinals - perhaps they are lined up between two glory holes and guests that came to take a piss can hear Karryn moaning - if they can hear her, they can approach a hole from the left or right stall.
Probably there can be two toys attached - one for pussy on the left and for anal sex on the right side.
5) Karryn can take cocks in left and/or right hand, pussy, mouth and ass - no mention of titjob yet.
6) There are 5 poses designed - sitting normally, sitting on the left and right and standing on the left and right
7) The limit of people that can spawn is initially 5 but can be increased or decreased based on prison edicts like hire cooks or bulk food supplier or glory hole reputation
8) There are three type of queues: urinal (taking piss), stall and washing - apparently if there's too much noise from Karryn, guests from the queues can hear it and come to the stall on the left or right.
9) After an orgasm a guest leaves the stall and joins washing queue.
