Not encountering a blocked toilet, an overflowing bin or a drunk homeless woman demanding I give her the £5 in my purse instead of coins, I suppose.
Most public toilets are horrible places, often isolated and with terrible facilities. Often with one locked cubicle occupied by someone finding a vein, when I was a teenager.
The idea they're in any way safe, let alone places where memories are made, is profoundly ridiculous. The memory I most associate with public toilets is leaving with a load of cheap tissue stuffed in my knickers, because I don't go by choice. Oh and getting beaten up there in school by snobby girls who'd call you a boy, because girls are vicious.
The idea trans women (who have used them forever) going for a quick piss could affect that experience is deeply silly. As a gnc cis woman, it's never been them I feared. It's other cis women and violent cis men (who can hide there easily and wait for you to be alone).
Female toilets are places you get dragged into to be hurt, not safe spaces at all - some of us learned that young. Gay girls were too scared to use toilets when I was at school, for precisely this reason.
Transphobic myths about tw getting off on going there are largely based on weird porn. Hypersexualising minorities, and sexualising everything they do, is such a tired old trope.
Anyway, yeah, horrific places. They need urgent improving and to be made actually safe, not treated like they were sacred palaces of femininity before the current trans panic.
All the trans panic has done is made me more scared to go in one, which is so helpful during menopause. All the men fixated on trans people using them can seriously get lost and address their own behaviour.
