Be careful guys, they are chasing us in places where there is no other way to stop than double red or taxi rank ( like Shoreditch house ebor st ~) and will give warnings for not wearing your badge around the neck and picking up from taxi rank, i dont know what will happen if you will get 2 warning letters from TFL but is better to avoid. It happened to me last night even if i had my badge under the mirror where is more visible than wearing around neck, but they dont care , my guess is that they are somehow under pressure from black drivers
