I'm a session musician specializing in rare instruments, so yes, my fees are quite high because I have to pay back these instruments and I'm kind of alone in my field. Some guy tried to get a discount the worst way I've ever seen.
Client: Hi, can you play The Fairy's Dream bass, oboe, and ondes Martenot parts?
Me: Well, I don't know this piece. Who wrote it? Do you have a link where I could see the sheets or at least hear the parts?
Client: What?! Don't you know who I am?! I wrote this piece! Sorry, but I don't like to work with people not knowing me or my music... or at least not for your prices. Maybe if you gave me a discount...
My answer to that was saying "lol" and blocking him.
