Look both ways

My employer gave me a handy little guidebook to living in Qatar.
Women are to dress conservatively, meaning no bare shoulders, short skirts or anything transparent.
When sitting with someone, do not point the sole of your shoe or the foot at him (presumably if you're crossing your legs). It's insulting.
And when eating with your fingers in the company of a Muslim, don't not use your left hand. "The right hand is considered more appropriate because the left hand is reserved for personal hygiene."
Nice.
Finally, look both ways before crossing the street, then forget about it... Doha is lousy with roundabouts, sans crosswalks and often without traffic lights. Drivers here are sometimes stupid fast. They'll come flying into a roundabout and whip through the very next turn. If you're trying to cross the street, and there's a building or whatever, you can't always see them. As a result, when it comes to road fatalities in Qatar pedestrians account for almost a third of all deaths.
