patient expects discount


I am a dentist. Sandy, my brother’s girlfriend of 5+yrs and retired hygienist scheduled an appointment with me for Monday to impress for an implant crown and an abutment. She and I are also friends. She asked my office administrator the fees several weeks ago and said she could go to another dentist and get it done much less and she could get the abutment from her periodontist that placed the implant. I waited for her to approach me with this info. She did not. Yesterday, she called and scheduled an appointment for this Monday to have the impression to have the implant crown done.

My fee for this procedure is 1200.00 for the crown and 600.00 for the lab fee.
I don’t know what to do. What are your thoughts?
