I'm based in Saudi, and have been for six years. THe attitude to smoking has generally been very laid back in that everyone did it. However, the last few years, more shops and offices have clamped down. My office and the whole building is meant to be non smoking, but my boss smokes at least one cigar a day in his office ( next door to mine). Virtually every office has its own ashtray. THe more senior you are , the more you can get away with ( aint that the truth! ).
In response to the original question though, I vape all day long without interruption and without any problem at all. Take my PV into meetings and what not and don't have any problems or objections. In fact, I have loads of people asking me to get them an ecig, and I've tried getting a load into the county....but thats a story for another day.
