I can tell you why your doctors office is behind on appointment times.
All day long people come in for things that they failed to mention when they made their appointment. They are scheduled for a blood pressure check and follow up on meds. But really they have been having a little chest pain off and on for the last 2 months. So a 15 min appointment becomes a 45 min appointment.
Or little Billy has a sore throat and a runny nose. What do you know little Susie woke up with it this morning too, can we squeeze her in while we are here?
Joe hurt his shoulder last week playing baseball. He makes an appointment for that, but when he gets there, he wants the doc to look at his foot too. It hurts when he runs.
Then there is the guy that had the 2:00 PM appointment, but shows up at 2:30.

and expects to get right in. Sorry Jordan, those people go to the bottom of the line. We will see the 2:15, the 2:30 and probably the 2:45 before you.
This happens all day, people never tell that nosey scheduling person what they really want, so they can schedule the right amount of time. Or they feel free to bring along siblings to be seen at the same time, or they just plain ignore the most important medical problem, usually a big one that requires testing and detective work on the part of the medical staff. Instead of scheduling a complete physical, which they need, they schedule a follow up on the blood pressure.
For fotze's question, I have no idea why a doctor would not want to see you wife if she has too many medical problems, unless it is for a high risk pregnancy or something else that the office does not specialize in.
