This happened earlier and I'm still mulling it over. I think the woman was incredibly cheeky and rude.
The baby changing and disabled toilet are rolled into one and require a radar key to access. Was given key, then almost finished and was just washing my hands when I could hear somebody fumbling with the lock. They then opened the door (I have no idea why the use of another radar key overrides it being unlocked from the inside - it seems a ridiculous design). I'd been about to use the toilet myself, it had a special little chair to strap your child into so you could go to the toilet without holding them, but when I heard the door being messed with realised either a disabled person or another parent needs the room so I'll just leave. Bloody glad I didn't as it opened onto the entire corridor! Anyway, when the woman opened the door, she didn't apologise and close the door, she looked me up and down with a look of disgust on her face, closed the door slightly to see what symbols it had on it, then re-opened it, glared some more and said "are YOU DONE
" in a really angry tone. Wtf?! I was quite shocked. I don't know why disabled toilets and baby changing facilities are lumped in together, but that's the fault of the designer, not mine for using it. I was actually just getting ready to leave anyway and a bit gobsmacked so said yes. She then stood right in the doorway glaring at me and shaking her head in disgust, right in my way so I'd have to squeeze past her while she glared in my face. She was taller than me and intentionally sticking her face forwards towards me, following me around her as I left the room, almost like squaring up to someone and getting in their face, if that makes sense. I didn't think there was much point saying anything, and I also have her the benefit of the doubt and thought she might have a disability which means she desperately needs the toilet now so I'll let it go.
But I'm still a bit shocked about it now. I couldn't imagine ever opening the door to a toilet, finding somebody in there and doing anything other than instantly shutting it and apologising, let alone behaving aggressively towards them. So... WIBU?
