In homebase today, and the sign on the toilets said 'closed because of covid-19'. It's the same in lidl, b&q, and lots of other shops.
I was in london the other week and resorted to asking a church to let me in (must have looked desperate as despite the signs saying not for public use, the verger let me in!).
It's no good opening cafes and selling me drinks, it has to come out somewhere.
When will these places start using sense and opening up again? Today, I didn't need a pee, fwiw, but if it had been another day, or my period had been more insistent what would I have done? I had to drive home from the shops a few months ago or I would have wet myself.
