I feel like my ob/gyn was rude

I chose this practice because it has several certified nurse midwives. I prefer the midwife experience over obs. They don't leave your side and are super helpful during labor. Anyways, there are 2 male obs at the office too. The one I saw today was old and most of the reviews are positive about him. The first thing he said to me was " Hopefully this one is your last, there will have to be a last one sometime." This is baby number 6. I just said yeah maybe. The rest of the visit I just didn't feel the friendly vibe that other patients felt. He was kind of condescending. The more I think about his comment the more annoyed I get. I feel that it was inappropriate for him to voice his opinion like that right off the bat. I hope I don't see him again.
