Rude receptionist?!

Called my doctor's office today to look into prenatal care and the receptionist was soooo judgemental! He asked if the pregnancy was expected and planned, and he asked again if it was a "desired" pregnancy. He didn't need to ask three times if I wanted the baby, especially since I'm trying to arrange pregnancy care for me and the baby! Plus he said, "Well, you're so young, only 21..."
Okay, I might be young, but I'm married, I went to college, I have a job, etc. You don't know my life or my qualifications to be a parent based off of my age! 
So. Rude.
