lol - I see you've downgraded from "strong link" to "some signs".

Andway, even if there was proof to back up the claims do you really think Qatar would be that bothered? It's not exactly the most health and safety concious country, is it?

And even if you did have a right to challenge these issues (which I'm fairly sure you don't), do you really think they'd take any notice of you?

Good luck with challenging the mast next to your villa, and when that fails, all the best for when you leave Doha.
