Christian Medical College — Takes huge time for the doctor to see patient

Address:

Cmc vellore

We were asked to report to MRO at 4pm on Jan 12th 2023. We reported half hour before the time mentioned in appointment and now the time is around 8 but still the doc is yet to see patient.
Why is this?
Then what’s the use of reporting time mentioned in the appointment
Does patient’s time is not valued in the hospital?
I understand the doc time is valuable but where is the respect for other individuals time
