I change planes in Istanbul all the time and have never seen this in the middle of the lounge there. There is a mosque in the airport and people who want to pray go there.

Furthermore, while I have never worked in an office in a Muslim country, I'd be willing to bet there's little praying in the middle of the cubicles.

Next time you are transiting through Riyadh, try pulling out a cross and a bible and see what happens. (or worse, tefillin and a talit if you are Jewish).
