The DDA doesn't work very well because it isn't really enforced. If a disabled person encounters discrimination, they can't just ring up the disability rights comission and say "this happened! sort it!". They have to find the time, energy and money (a lot of disabled people are short of at least one if not two of those) to get legal assistance, assemble a case, and go to court. They then have to fight against the legal team of the company... so if you encounter discrimination/lack of access/etc in (to use a random example) McDonalds in Smalltown, then you have to be prepared to take on the entire legal team of McDonalds Restaurants Limited. Would you try that? Or would you just cut your losses and go elsewhere? (and if MOD counts as "the armed forces" then they are exempt anyway and can treat you like any flavour of shit they choose.)
