If you are going in the summer time, you will have to worry about the extreme heat more than anything else.
Like everyone said, drugs are a no no (even prescriptions)
they have zero tolerance on drinking and driving
Other than that it is all good.
My story: In 2005 one of my contacts found me a decent potential job in Dubai. I went there for the interview (was supposed to be a formality). I arrived at the office where I had the interview, decided to smoke a cigarette outside (stopped smoking in 2007)
BAD DECISION: I was sweating from all over my suit. It was disgusting. Went to see the interviewer and he asked me the first question:
So tell me how is Dubai treating you? you like it here?
I told him I am not sure that I can live here
Was one of the funniest moments in my life
