I agree with it being silly debating over your rate with a wanna be (but incidentally never-will-be) client. He probably started the text conversation, so to say "don't text me again" is just annoying. Be glad he ended the conversation. That's just time you get to keep for your sanity. LOL. When I get an email that even slightly indicates haggling...."delete". You should be happy with your rates. Its an exchange. If you feel good about what you are getting out of the exchange, then good on ya! If not, then you have the right to change YOUR rates based on YOUR needs. End of story.
I don't agree with upselling either. What's available is what's available and I don't think there should be extra charges for what you offer to begin with, but again, that's just me. As ThePrince and a few others have said: her price is her price. For that guy to say he wasn't into paying that price? To me that meant "I'm not interested in seeing YOU." Sorry you had your time wasted hon. But I bet it wouldn't have been a good session anyway, so lucky you.
