Any question answered...

Here's a delight.
I regularly catch a train to visit my father in his care home in Chislehurst.
There's a cab office, adjacent to the station.
My journey is completed courtesy of the Brompton.
Last Saturday there were 3 or 4 men outside the cab office.
No one else anywhere near.
The smell of smoked dope was very evident.

Not exactly confidence inspiring if you are a cab user, or sharing the road.
I understand the none of the said men could possibly have been cab drivers.
