Strange Clinic Hours!

I just called the clinic (assigned by my company's HR) to arrange an appointment to come doen later in the afternoon for my pre-employment check-up. And I really was shocked to hear that the clinic only opens from 9:30am - 12pm on Saturdays!

Of course, this is not wrong to work half day on Saturday, but isn't 2 & 1/2 hours rather short to come all the way to work just to work that meagre 2 hours or so? Plus, since this clinic also sees pre-employment check-up for newly appointed staff, the duration should normally take about 20 - 30 minutes or so, considering the waiting time & all.

So how in the world would the clinic only open & be able to see only a handful of 5 patients on Saturday? Wouldn't it be like almost redundant to everyone else? To me, my thoughts are - "Duh! What's the point?"

Might as well open for slightly longer working hours on a weekday, so that more people can go for the check-up or see the doctor, instead of coming down all the way to Orchard on an early Saturday. Btw, the clinic closes at 4pm on weekdays too... what kind of working hours is that? Just hire part-time staff? Part-time doctor? What kind of management is this? Terrible!
