Be prepared
In the closet of my hotel room in Shanghai, there is the usual stuff-- some hangers, a set of slippers, the laundry bag and request form. There is also a gas mask. It claims to be effective in case of fire, but is also labeled, "anti-smog, anti-carbon monoxide, anti-hydrogen cyanide, anti-sarin."
I hope I don't need it! Can you imagine placing such an item in an American hotel room?
