Chin implant removal refund. I want to know what is acceptable and not out of line as a patient here so please answer honestly

I went into my surgeon to get rid of my double chin and loose playsma muscle, he suggested a chin implant to go along w it.I hadn't ever considered an implant but reluctantly agreed as he said it would enhance my results and I was worried he wouldn't do the other procedure if I declined the implant.I quickly realized I did not want this and had him remove it within a week.Is it weird for me to ask for a refund on my chin implant that I never wanted?I wasn't planning on it but just thought of it.
