Having used the tube for several years, I've never yet encountered a
revenue ticket inspection on board a tube train or within station
passages [1]. Do LUL ever bother checking tickets randomly on the
network or do they let the ticket gates do the job?

[1] I did get my Oyster card swiped by someone on board a DLR train to
Custom House last Fri. If I hadn't touched in my annual Oystercard,
would I have been liable for a penalty fare? The reason I ask, is
that the station tannoy always reminds PAYG customers to always touch
in and touch out, but it doesn't mention annual Oysters.

I've not seen an on-tube check in 3 years of mainly central line,
however collegues have.

Have seen them at interchanges though, Notting Hill Gate is a popular
one, and I've seen them at Bank (presumably because of people changing
from the DLR?) Wasn't checked in either case as I just continued
walking at a high speed and they decided it wasn't worth it.
