I've seen similar conversations in other areas - sometime the "pro" deals with the request diplomatically, sometimes they are far from diplomatic - but not like that - which is how I am sure most would love to respond.
However sometimes you can work a discount in... I had a conversation with our wedding photographer which went along the lines of... "yep we'll have you, can I see the contract before I commit?" "Certainly, I'll email it across". The contract came and was really really bad.... I phoned him back and told him, we agreed a reduced fee and I rewrote his contract. He was an ABIPP, surly if you run a business you need a contract that is fair to both parties as well as protecting your own work? He had also been trained by pro who is a renowned cleb pro (not mentioning either parties in case it tells anyone who the wedding pro is I'm talking about). Not that this makes them a good photographer - but surly from a business point of view he would have been teaching his students properly as he himself would be dealing with hard hitting managers, publicists etc.
