Does Senior Management Ever Use Rest Rooms?

It is more than 2 months since I joined my new company, it’s an amazing place. Of all the amazing things I have noticed so far the most amazing one is that I have not seen any of the senior management ever in any toilet so far. Even though my seat is very near to our COO’s seat and I see him going in and coming out of his cabin so many times, I have never ever seen him going to toilet even once, which has kept me wondering for a long time now. There could be many possibilities for this:
a. They have separate toilets, which are probably camouflaged as meeting rooms or restricted areas and can be opened only by special access cards or finger print scanning.
b. They take some sort of medicines to control their bladders or have got them removed altogether.
c. Possibly they do go the toilets meant for lesser mortals but at the right time, when no one is able to see them. Having toilets under camera surveillance is a preposterous thought, having toilet gates is not. There could be someone monitoring the people going in and coming out and then letting the COO or others in senior management know (by turning-on the 'all clear' light in their cabin) the precise movement at which coast is clear.
d. Another possibility is that they have done some trend analysis based on the peak traffic and avoid those rush hours. In the unlikely event of being seen by a lowly employee it is very easy for them to pretend that they are on inspection and checking if everything is all right because they belong to, well…senior management.
e. Another advantage of being in the echelon of management is that you can go anywhere you wish and you need not answer anyone. A sentence like ‘oh, I’m entertaining a client’, when you are actually answering nature’s call at your home, would mean that people should not dare call you for next hour – enough time to go back to your home (which is again hardly a kilometre away, another advantage) do your ‘client entertainment’ and to come back. And frankly, who will dare question them even if they are late by 15-20 minutes?
