The thing is that models are going to meet all kinds of personalities and need to be on their toes and read the energy of the shoot. This photog did not want to interact with the models; he was focused on the shoot and idle banter is not his thing. The rule of thumb is to keep a low profile, do your job and only engage if a professional on the shoot starts an interaction. I am sure there are tons of 'jerks' in this industry and you have to know how to handle the situation or you will get a reputation for being difficult. I don't think it takes much for word to get out.
