Feeling comfortable on set

I had a meeting last night about a music video that is meant to start shooting today.
Basically, they were going to start my scenes with a "snuff film scene".
I was supposed to turn up in this underground garage at 10pm, where I'd then be tied up in my underwear and threatened- making for some interesting footage for that snuff film sequence.
Interesting!
Fortunately, there was another girl at the meeting yesterday but somehow I must have missed that scene in the script.
The guy was nice enough and seemed cool and straightforward, but I had to ask him who else was going to be on the set. Fair enough, they want to shoot late-ish in order to be free from disturbances by residents trying to park their cars, but still- 10pm with a crew of 2, and me in a basque and suspenders!?
In any case, I was reassured and ready to start shooting today (just gotta mention this is all unpaid again, let's hope the band make it big), when he called and cancelled me.
So instead of hanging around a dark garage half-naked, I will be tucked up in bed drinking tea, for exactly the same amount of money (i.e. sweet FA).
The only thing is, I already splashed out on a travelcard...
