Picture the scene : Strolling through the London streets, passing through many amazing shopping places, looking in awe at the Big Ben and then you decided to go to London bridge but what you see is not what you expected.This is not the bridge you wanted to see or you’re on a busy train on the London Underground when you accidentally step on someone’s foot.Your fellow traveller mumbles an inexplicable apology, and you respond by making eye contact and initiating a conversation. Silence envelops the carriage and everyone’s gaze drops to the floor, while the other person pulls the face of someone who’s been told they have seven seconds to live. Five seconds ago.You’ve just breached London social etiquette. Don’t worry, the most you’re likely to suffer is a tut in your general direction – that’s as confrontational as most British people get. Even so, if you’d rather blend in like a local when exploring the capital, keep these dos and don’ts in mind.
