That is interesting...
One thing about those roles you brought out (Gym Trainer and Bartender) is that these roles should prefer using sims that live in the same world or are evicted from there. They somewhat still prefer, as when I made some sims to be Tomarang and Chestnut Ridge locals, they were chosen as bartenders fine. Yet the other worlds still had a chance of recruiting them as a bartender. So yeah...
So Get Famous breaks that filter term then, having the game recruit sims that are not "living" in that world... Interesting... Both of the sims brought out in the example are unemployed (they do not need a career to appear in their original role), so simply giving sims a job should prevent them from randomly becoming a bartender.
Theory why it might break the filter term? Hmm... Both Gym Trainer and Bartender roles exclude famous sims (at least 1 fame level and they're out). Yet the template making them does not guarantee that new sims generated have exactly 0 fame points. Yet at the same time, I don't see more famous sims generated...
The only theory I can suggest here is that the game creates a sim with some fame points (but not enough for the 1 rank), gets excluded from the filter, and a pre-made sim without any fame levels is chosen. While I doubt that is the case, the reason must be hidden within the fame system...
