artistsbeware2_archive | Client with difficult circumstances

Edit: For everyone telling me to refund, i have previously stated that there was no transaction of funds due to me not having all the information. I wasnt going to send an invoice until I had everything i needed first.

So I gad a friend come to me wanting a $90 commission of their character and their GF's character. Sadly, their girlfriend lacks a reference sheet, and is making things very difficult for my friend to get artwork done by me as a result.

My friend was given information that was lacking major important details (namely color information and pattern details, they only inclyded body shape and breast size but didn't provide anything else that was of real importance such as a color pallet, fyr design, hair style, ect...) that he relayed back to me, and in an attempt to make it easier on my friend and save money, I offered to make his partner a reference sheet for the $90 instead. She refused but still wants art drawn of her character and to have her bf pay for it.

I personally dont like the idea of having to charge my friend a fee for not having a reference sheet (it's listed in my ToS to have one or be fined a $5 fee) because his partner refuses to get one made. I want to draw the art because he wants to make it a gift for his partner, but his partner is making it both difficult for him in the sense of giving inproper information/facts about the character to relay back to me, and myself on the matter of "I dont want to be held respobsible for drawing a character wrong because she lacks a reference sheet."

I was trying to be nice and offer an easy alternative that will not only help me, but furture artists who are tasked with drawing this character as well who like reference sheets and make it easier on my friend in the long run.

My problem now that i need advice on, is what do i do when a client wants art of x-character as a gift but their partner is making it extreemly difficult for my client and myself on getting a proper transaction and order to be made? Do I step away and decline the offer and miss a chance on making a sale, or do I try to draw the art and risk an unhappy client as a result of improper information? I've expressed my concerns that this person is making it very difficult on my friend and i, but im ultimately at a loss on what else to do. I've never had to deal with this sort of problem before in a long time if at all where a client wants art but their partner is making a normally easy process suddenly very difficult.

Advice is very much appreciated.
