How do you interact with celebrities? "Attempt Introduction" Failures

Generally I have my Sim ignor them as much as possible - as my female does that idiotic excited clap thing that annoys me to no end - so unless a celeb comes up and start talking to my sim I try to force them to move on. If that doesn't work I send them somewhere else out of that town.

I rarely have even my few sims that live there hang around any of the venues there - I send them to other towns when my sim is through with their gig - off they go.
