My OB had told me up front that there's a high chance she won't deliver me due to various reasons but I was okay with it. In the end, the doctor that delivered was great, and I felt like it didn't really matter since they don't come till the end anyway!

My newly pregnant friend is super paranoid and wants to find someone that can guarantee delivery even though I told her there's always gonna be exceptions (on vacation, not on call, with another patient, etc) unless she has scheduled c-section.
