Dubai Signs

 The sign noting that it is prayer time is from the City Centre shopping mall.  I didn't see a mad scramble for the prayer mats as the call went out; most people seemed to just go about their shopping, wearing Western clothing and other secular business.

The second sign probably isn't very legible, but it's the best shot I could get after dusk.  The third line reads, "No kissing or overt displays of affection."  The fourth, closely related, reads, "No dangerous activities."

They take their mall behavior seriously in Dubai.
