Your right, but it comes down to what is reasonable. A solicitor visiting a clients home is reasonable, after-all everyone is entitled to legal advice and it's on a one to one basis.
Contrast this with the Business Link who run many courses, which are very popular.
Is it now reasonable to exclude or interupt the course for all others because of your special needs? (Which you failed to mention in advance)
Once you are on their premises they must accommodate you as best as possible, regardless, but before that it's upto you to atleast try and make arrangments - or to make it known you are disabled, because as you can see, people will go out of their way to help.
I personally find your attitude disappointing. After reading your post it sounds like you had a tantrum over the distance and straight away phoned the DRC instead of phoning the Business Link and explaining the situation.
It's not a case of "tough luck", but facing facts at some point unless you put yourself out it always will be "tough luck" (That goes for you, me, and everyone else!). Thats life and no one is here to support yours no matter how badly done you feel - you can always do a little more.
