Is the former ticket seller at Bow Road walking up and down the
platform at night to "reassure" me and enforce the smoking ban? No -
because that duty/post no longer exists on the rota there. He or she
might be filling a vacancy at a busier station, or be in training for
driver, but the idea that LU have introduced some form of "reassurance
patrol" is just plain lies.

The ticket office was the one place passengers could expect to find
staff, not in often anonymous control rooms. And help points are a
great way of attracting attention to yourself, not ideal if you want
to 'covertly' draw staff's attention to something (you think you're
being followed, kids smoking dope, the muttering nutter with backpack
etc...).
