This poster appears at various locations around the Underground network (this one at Hainault station).

It reads Top up your Oyster when you pop to the shop - and avoid the queue at the station

It may as well read Go away and buy your Oyster top-up somewhere else - and if enough of you do that, we’ll close this station’s ticket office.

It is a graphic example of how London Underground is deliberately driving business away from its own ticket offices in order to prepare for ticket office closures. And it’s a graphic example of why staff need to get active in RMT’s fight to defend ticket offices and jobs.
