There aren't all that many Underground stations with public toilets,
either. The only one that springs to mind immediately is Barons Court,
we'd just travelled from Hounslow West and my other half was absolutely
bursting by the time we got there.

More than you'd think:

That's not toilets at TfL stations, it's largely toilets somewhere near
TfL stations. The clue being the black lozenge "outside the gateline".

With a side order of "Dagger": not managed by TfL.
