Media propaganda, don't do anything stupid you won't be put in jail. No crime, Waitrose, Costa, M&S, KFC, Pizza &Pasta, it's all very Westernised now. World-class public transport systems and taxi's cheaper than an oyster fayre. I wouldn't be put off going to Dubai with the worry of breaking a rule.
Maybe you might be put into jail for investigating the country's security systems otherwise I wouldn't worry at all.
