Hey, so, maybe this was intentional, and if so please do ignore this. But I noticed that when I was going to jobs, I could never encounter any of the feeder personality types, at all.
I had a look at the code and this seems to happen because all 4 feeder personalities, and the "bubbly", "ambitious", "sloppy", and "shy" personalities are all set as used, even if you never encounter anybody since you started the game.
Because applying for a job generates a new girl, and a generated girl will never use a personality marked as "used", you will never encounter a feeder when working. Or at least from my limited searching, that's what I found.
Again, maybe you meant for this to happen, if so sorry to bother you with this random observation. But I thought I'd bring it to your attention in case this was not intentional behaviour.
