When I retired my treat to myself was membership of some London museums and galleries.
Used to love the V&A members room - tiny and hidden away - nothing showy.
They redid it, moved it, bigger, proper bar, more food choices. Gender neutral loos. Basically a trad ladies loo, sinks in a row, mirrors, cubicles.
I met some very embarrassed blokes the first time I used it. The last time it truly smelled vile. Such a stupid idea. The old loos were unisex/accessible/ fully enclosed with sinks.
