Didnt know that. Good opportunity to vacuum the car whilst you are there. It does make me laugh though that people go to the garage for "air", I just can't believe people own a car and don't have a way to pump up the tyres. Inspires no confidence at all that many people even ever bother to check their tyre pressures.Apart from the roof, I don't see what's different from any other charging hub. Good luck to them though, more is better.
Taking their 'pit stop' idea, one thing I was surprised not to see at eg Gridserve, was easy access to air/ water/ vacuum/ screen squeegee while charging. Some people are happy to twiddle their thumbs in the car or go to the shop/ cafe, but others could make good use of the charging time giving the car a proper pit stop.
