When I looked, I found that many shelters display a 'No Smoking' sign,
whether or not they have three walls but some do not.

This was triggered by the Esher High Street stop (back wall only, sign)
having its bench removed (temp I hope) and a guy noting he was on his
way to Guildford to answer a charge of smoking in a Leatherhead
shelter. Both have TfL services.

Google didn't help much but a ministerial statement of intent to make
all shelters 'No Smoking' turned up plus a failed Scottish prosecution
and a three-sides everywhere but otherwise "only on private land" note
to the original regulations with an "adjacent to a bus station"
example.

Is it a local authority option or random error ?
