Are you kidding me? I'm in the basement and I gotta make a deposit at the First Bank of Vitreous China, and here's the sign I'm given?! [flips up middle finger] Here's my sign for you and your toilet room apartheid.
I've been in this toilet room, and I think I know why they haven't retrofitted it. Making a stall inside the toilet room itself wouldn't be that hard, but there's a rather circuitous path from this door to the door of the actual toilet room. I suppose they could put automatic openers on the doors--this one and the toilet room door--but those are generally $1,000 each and require running power, etc. to the doors and possibly changing doors and door frames. Again, we're running into the equivalent-experience thing here.
Still, though, if I had to pee and I was in a wheelchair, and I saw this sign, I'd be mighty, um, pissed.
