How intrusive are fame and celebrities?

I wouldn't say they are very intrusive but they can disrupt your flow. There is always a celeb sim who shows up on a venue lot even without the nee lots traits so I think that needs to be changed. I would like it if the celebs only appeared on lots with the new lot triats or lower their spawning on lots especially higher ranked celebs. They also needs to change how service sims handle celebs as they shouldn't stop doing their job and celebs who are doing a service should focus on doing their job.
