Liberty’s - yes - it’s been like that for ages. I was bursting (I usually avoid public loos) and went to the ‘ladies’ (on some back stairs - so out of the way) and there was 2 or 3 cubicles and a disabled one. The sink was communal.
Also the lights were out in the staircase so they were dim (and like usual fancy blocks, just plain concrete back stairs). So the mixed sex loos were off the beaten track on a dark back staircase.
So of course the women and girls queued for the other cubicles - most men wandered in, looked shocked then apologised and turned tail. One aggressive and grumpy man shoved last us all, grumbling - and went into the disabled loos (he looked fine - you never know) and slammed the door.
There was a member of staff waiting too - she did utter apologies to the queue of women when the men came in.
He was greeted with the death stare by the queue when he got out though.
I got onto that website that lists loos and told trek that this loo was unisex and they ought to note which ones were.
It sucks. I suspect Selfridges are the same (may say ladies but who is going to challenge a man?). Don’t know about Harrods.
