s aren't theirs but its a courtesy they provide anyway.
I don't know about optometrists but I work for an ophthalmologist and there is a separate charge for refracting a patient (coming up with the patient's prescription). Some insurances do not cover this and it then becomes the patient's responsibility. If a patient does not pay this fee after they have been refracted, the doctor has the right to withhold the prescription until it is paid. That is the only time that I know of that a prescription can be withheld and, like I say, that is the case with ophthalmologists but I don't know about optometrists.

The pupil distance is a side-to-side measurement measuring, of course, the distance between the pupils. Obviously once this measurement is taken it doesn't change because your eyes don't move.

My boss takes the height (bifocal measurement) with the patient wearing the glasses. It can be different from frame to frame, depending on the size of the frame and where the patient feels that the frame is sitting most comfortably on their nose. At my office that is never put on a patient's script because of the fact that it can vary.
