Aggression, road rage, bad language, offensive hand gestures and spitting on the streets is not tolerated in the U.A.E. and can result in deportation or a term in prison.
Smoking in public is also frowned upon. Avoid the cigar or cigarette if under 18, or if in malls, offices and on government property. Those over 18 can always go to nightclubs or bars or specific areas designated for smoking.
