This is a situation from long ago in my career, but as I'm working with the same actress, again, and it came up anecdotaly, I thought I'd pose it to the forums as a good "what would you do?"
The cast had left the theatre after the evening show, and between my post-show duties, locking up, and switching the laundry, I left the theatre about 45 minutes later. Only to find my entire cast and a few of their signifigant others standing around the parking lot.
During the show, one of the actresses car had been stolen.
In aforementioned situation, what are your responsiblities as SM?
As it resulted, the actress wasn't too upset (she hated her car), and even found a $100 bill on the ground, where her car had been, and took her castmates drinking with it.
As the parking lot was rather isolated, and the police had already been called, I went out to the street to direct them back to the site, unlocked the theatre so the cast could go back in and get a bottle of their wine from the fridge and some cups, relocked the theatre, ensured the cast would dispose of their cups and the empty bottle in the dumpster, made sure the actress had a ride home, and left because it was very late and I had an hour drive home, and there were seven people standing around the parking lot, so everyone was safe.
I sent an addendum to the performance report when I got home.
What would you have done?
