It's good they are doing this. I'd like to see the same in Qatar to clear up any confusion. Leaflets or posters at the mall explaining the respectful dress code would certainly help, or even people posted around to politely point out that what someone is wearing is inappropriate.

However, I don't think these leaflets at the Dubai hotels would have helped in the Michelle Palmer case. She'd lived there for something like two years so could hardly plead ignorance to the rules!
