Since almost nobody (apart, of course, from me) seems to have any courtesy or good manners (and in this I naturally include Mither) it seems remarkably obvious that an enforceable solution to give wheelchair users the necessary priority is necessary. And, as I pointed out, there is an easy one. If I am correctly informed Stagecoach apply it (see above).

If there are no wheelchair users there is no problem.

If First Bus choose not to include a term like Stagecoach's in their conditions of carriage, that is a deliberate choice. Shame on them.

The reason it needs to go to the Supreme Court is to get disabled users the access they need when the fully abled will (disgracefully) not voluntarily do so. And remarks like Mither's make that very obvious. Shame on Mither. A magnificent example of a socialist. Not.
