So it's a regular and significant occurrence? In that case you are right to be concerned and raise the issue.
We do thousands of journeys each day so some might say it's not significant enough (one of the counter arguements being used). But aside the impact to the company there's also the impact on the other travellers.
What if Rita is on her way to the hospital to see her dying husband?
What if Sue is on her final written at work for being late, has now caught an earlier bus so she doesn't get fired?
What if Bob, who's a carer and on his way to client?
And they all get delayed by someone who needed a carer and travelled without and had an episode
In the county where I work the figures show that almost 80% (78.9% for the pedants) of passengers use an authority issued free pass & has increased year on year for the last 9 (this includes OAPs, there's no separation of those figures available, at least to me). The national average is 32%.
The local authority simply cannot afford it so I get why they're looking at this a cost-saving issue, whilst we, the operators are arguing the health & safety side and service disruption as a greater validity.
No-one is saying that disabled people cannot travel, simply that if they declare they need a carer to travel (in order to secure a +carer pass) then they must have one to travel.
Yes, I understand chronic disabilities, I have one. If there are occasions where I would need a carer to travel with me then the Mobility component of my PIP is there to cover that additional cost.
