And if the level of publicity about OEPs at stations served by SWT is

OEPs?

Every SWT station got the "Oyster PAYG on NR" leaflet on its rack which
has OEP information (just like the LU leaflet with the same title).

I can't say the leaflets leapt out at me when I was last at Waterloo or
Ewell West, to take two extreme cases. And it's all very well being buried
in a leaflet but are there any posters up around ticket offices that
actually try to grab passengers' attention?
