As a fellow photog, I feel your pain - believe me when i say it is a hundred times worse for me with a lighting full crew and location money flying out the window when some stupid and selfish hooker flakes - compounded into that is the scripts I have to do for adult xxx features - which in most cases means multiple days for the talent - I can't go into it but I have been screwed pretty bad sometimes - I get upset even thinking about it. It costs real money and that's fucked - there has to be an answer - I agree and I welcome any ideas.
I came across one photogs answer to this - it's actually pretty entertaining - I have thought about doing the same thing myself - but fortunately, I have not had that bad of a flake yet for a still shoot. He calls it the shitlist.
Check it out - the guy is Kelly Lind - he does some pretty cool pics too:
