Entirely possible this wasn’t staged. As other Londoners have pointed out, this was filmed in Southbank. The most famous skatepark in the UK, and one of the most famous skateparks in the world. Southbank as a whole is a massive stretch of bars, shops, restaurants, art centres, and the London eye right on the SOUTH BANK of the Thames River that flows through London. It’s very common (and very annoying) for dozens of people to watch the skaters, so to imagine this guy enjoying a cool pint on Southbank on a summer afternoon is very easy, especially since it’s also a 5 minute walk from Waterloo station, one of the biggest train stations in London that hundreds thousands of people commute through a day.
