That isn't really true though, unless your itinerary is focused on the centre of major cities and you're determined to stay in chain hotels, eat international food and get taxis everywhere (if your main experience of travelling overseas is business, it might look like this)

Sure, Premier League branded football shirts turn up in the unlikeliest of places and it turns out that actually people don't wear what the internet says is their national dress all that much - that's one of the first things you learn when you travel - but there's plenty that's different, even if you can only communicate with the English speakers.
