> The doctor would give appointment times that assumed he'd spend 15 minutes per patients but he was friendly and patient with answering questions so he'd always end up being very late by the time evening came.

I have a doctor like this, and it's totally worth the wait as she actually listens to people and provides useful information. I do generally try to get a morning appointment with her though, as otherwise it can take a loooooonnnnngggg time.

Yes, the wait is annoying but I do love doctors like this. It's a sign of a great doctor. Just always found it funny that they don't just adjust their appointment time given that the estimate they have is never actually attained in practice.
