But if the other toilets don't exist, or are closed, what are people supposed to do?
I fully support disabled people having access to toilets kitted out for them.
I don't support disabled people who think their needs trump another person's all of the time, under any circumstances whatsoever.
If you, or any disabled person, need to wait because someone is already in the toilet, that person will only have used it out of desperation.
Not all people with a mobility issue have urgency, or need to change a stoma bag. Some will be happy and not inconvenienced at all by having to wait 2 minutes.
People's needs differ. Some need more space if they have a wheelchair.
Others need a toilet fast because of some medical issue.
Other people need a toilet when the others are closed or out of order.
No one should judge, because people with IBS, or bladder diseases, or who are on medication that makes them pee more or have diarrhea don't go around with a label on their heads.
If anyone uses a loo with 'accessibility' it's because they need to.
