Zig-zag is three uses (in-out-in or out-in-out or purchase-in-out) in
quick succession, right?



What use would that be to anyone? I mean, what scam would be pulled
by that means?

When I go through the barriers at Charing Cross platforms 1 - 4, just
miss my train and have to head for platform 6 for the next one, I've
never understood why the gates won't let me out. What scam is being
prevented by it?
