I asked a steward about this last night, who, to paint a more positive picture of them was actually reasonable.
I normally enter via the Dolman entrance where no checks are made before the turnstiles. Yesterday I came in from KFC and was stopped and asked to show my ticket.
When I asked why and the difference between the Dolman entrance the rationale he gave was “this route and the whole back of the Lansdown is a public access area usually so on match days we ask to see tickets”.
Perplexed at the answer I showed my ticket and carried on.
If it’s a public access route why is there a need to show tickets? To the above point what if someone just wants to walk along the back of the Lansdown. Maybe go to the shop, maybe get a drink but not watch the game.
Given you need to show your ticket at the turnstiles it does seem rather pointless.
