You must be one of the company folks to say such a thing.

When you hire Western people, you should tell them truthfully what to expect before they arrive. Nobody would be stupid enough to leave his comfortable home, travel half around the world to end up in a dirty hole with coakroaches in the end. While you folks may be used to building up companies from the bottom of the barrel in really unfavorable conditions, this is usually not the cup of tea for Westerners working abroad. In the first place, be honest; and it seems you haven't been, hence all the complaints, which I believe to be true.

Don't ever think that anyone here in the West would really care to travel half around the world just for a disorganized and dirty place like yours.

Do your homework before inviting anyone from abroad! Plain and simple.
