Sorry, without playing the paranoid card, I will refrain fro giving the specifics because I have heard and actually witnessed moments when some jobsworth has either reported or reprimanded a worker who dared to show some kindness, be accountable, or show initiative, as it goes against the grain of the local ‘culture’.
This is something I highly suspect would happen with this lamentable scheme. So for that reason I will just say that it was on a weekday and somewhere in West London.
I have since given up on trying to get a Boris Bike, the system (especially the customer service department) is a joke. For the moment, I’m either using my own bike, or the tube.
