Gents toilets at The Hawthorns

Like the sides of buses and phone boxes rules, a listener emailed in to suggest that it should be a truth universally acknowledged that no quality cinematic entertainment will be advertised in the small poster space above the urinals at West Bromwich Albion's home ground.
