Phone out of juice? It’s possibly the worst thing to happen on a journey home (other than falling asleep and waking up at Morden). How the hell are you meant to insta-stalk what everyone else is eating? But running out of battery on the bus may no longer be an issue, as London buses are installing USB plugs. If you’re lucky enough to use bus routes 507 (Victoria – Waterloo) and 521 (London Bridge – Waterloo), then you may be able to grab yourself one of the 12 charging spots that will be installed across 51 vehicles.
