Only in the privacy of your own home should you consider going in for a kiss. Public displays of affection – or PDAs as they are joylessly known – are forbidden in Dubai, and can land both parties in a lot of trouble. You can chance a cheeky snog in a lift, but you run the risk of the doors opening before your floor, exposing your misdemeanour. Even the back of a taxi is dodgy ground for kissing. If your taxi driver takes offence, he may well report you to the police. You can see why British couple Michelle Palmer and Vince Acors caused such a stir back in 2008.
