Why? Have they got something to hide?

I use them a bit, partially because when I have a side bag it's easier to
get through than twist through the regular gates, but also because the
Oyster readers on the WAGs are custom built-in to the gate and I find them
more consistently reliable than the readers added to the regular ones, where
on a number of occasions I, or the person in front of me, can't get through
on the first touch.
