Ah, the old "running out of paper for tickets trick"..........otherwise known as "give the bloke on the gate a fiver"
They must have moved him from the disabled exit gate to the away end!
blue button, press option 5, do not pass go, use turnstile 7 (that's the dodgy one, just give the bloke a fiver) stay hiding in the Hobgoblin, or just stay at home. Cos that's what they do!
