Thank you! Haha! Yes, I need more of those fancy vacations in the backcountry, sleeping on the ground... Actually, that is my kind of paradise!
Fortunately for me, after being in the business for 20 years, I'm in pretty high demand and I don't need to worry about losing one potential client. So I kept it simple and emotionless:
"Hello. Thank you for your interest in my photography services. I’m sorry but I don’t feel comfortable shooting for someone who is asking for a $300 discount. Have a great day."
I'm hoping that get's all the points across quickly, in only a slightly insulting back kind of way...
Have a great day @prettynicevideo!!!
