Actually, no.
Until as recently as 2019 I remember using changing rooms with curtains, and separate facilities for males and female.
You either have a very short memory (might wanna get that looked at) or a very dodgy hard drive (ditto).
Sorry, but this really irks me! Most British changing rooms have been gender neutral since as long as I can remember. This store has private lockable cubicles.
This is propaganda to play to a gallery of bigots and possibly people outside the UK who have literally no clue.
