Getting on the tube at Tottenham Court Road just now, I noticed that one
of the little advertisement posters had a small sticker on it, as is
sometimes done by protesters of various kinds.

Except that this one said something like:

Using prepay on your Oyster? Always remember to touch in and out
by putting the card flat against the reader.

Huh? Who would do this unofficially? Yet why do it officially?

Is this an intriguing marketing strategy? Your eye is often drawn to
the defacement stickers... perhaps TfL are using this to their
advantage?

It does seem rather odd. Was it a TfL poster on which the sticker
appeared?
