I use the 'disabled' loo at work to get changed, have a quick wash and other things.......
Our 'disabled' facility is brilliant, it has a pull cord light switch, fold down hand rails for use with getting on/off the toilet, loads of room (to swing a lion), a wash basin, hand towels, toilet roll and even has a custom-made wheel chair logo on the door.
But...............
Whichever bright spark 'architect' that designed the building thought it would be great to put the disabled toilets in a part of the building that's inaccessible to wheelchair users.....!
This is due to the width (or more accurately) narrowness of ALL doorways that lead onto the corridor that the toilet is in..................
PMSL (or waiting for the loo in my chair)
