Yes on paper there are a lot of laws , the golden rules are :
Don't get caught if you are pregnant and not married
Don't get caught in an affair , basically don't screw with the locals lol
and Gay men ! well ... I have not seen a gayer city then Dubai ... a straight couple not married have more chances of ending up in prison then 2 men kissing ! FACT lol
Straight male cabin crew ? really ! All joke aside, Dubai needs you more then you need it ! FACT
Now of course if you gonna be stupid and get drunk everynight ! well you might as well keep your suitcase packed !
... and keep in mind now that recruitment is back at full mode again, Golden Calls are gonna be long in waiting ! an idea, Emirates hired on average +-400 crew per month last year ! and they are finishing up building another big concourse !
Patience my friends ! all in due time
Good Luck
