So the photographer who booked you canceled at the last minute and then had the nerve to have his assistant do the dirty work, huh? Either he was sick as a dog, or he's too full of himself. If he's too full of himself, then all I can say is "la-de-freakin'-da." Not cool, not professional. Heck, even if he was sick and unless he had a major-bad case of either laryngitis or throat cancer, he still should have done you the courtesy of picking up the phone and giving you a call. If he thought his work was more important than being courteous to you, to to anyone else who models for him, good luck, bub, booking more shoots. Obviously he's already put a booking with you in serious jeopardy. But then I'm a stickler for simple courtesy (even if I blow it sometimes; I am great at giving apology, though), and on the few occasions where I've worked with people, I've always been aware that while I may be "the artist" the work is really a collaboration between me and the model--fat lotta good being an "artist" when you have no subject though. Just my ever so humble opinion though
