It's hard to predict just how long an appointment will take. Some have been done in five minutes, just a brief check-in and new prescription, and scheduling half an hour for that would mean twiddling his thumbs for twenty minutes he could have spent helping someone that arrived rather punctual for their appointment. I think scheduling for the average appointment but allowing overtime for those who need it is the more patient-friendly approach.

You got downvotes for it but nah, it's on the Dr if this is a regular occurrence. Once or twice or going over a min or two is fine, but regularly being 45 minutes late (hello my last Dr) is a sign you've lied to everyone scheduling an appointment about how long they are and when to even be there for one

Exactly, but if you the patient are late or a no show, then here's a $50 fee for you.
