I agree beauflow that corporations tend to make many decisions that don't exactly fit the human rights bills. However, I also acknowledge that corporations under many governments are left alone and can deviate from and law in place if they feel it somehow impedes the business be it cost (which is usually the biggest reason) or something else. The laws tend to bend in favour toward businesses because they are the ones wwho pay big bucks to support politicians.

That being said, I don't know if there are legal aid services that give free consultation about siutations like this. Usually one person is no threat to a business, but many people can be a threat. Petitioning is an option, to collect signatures to show that more people agree with you that this cannot be accepted. Writing to your government respresentative in the area could help some also. It wouldn't hurt to let more people know about the recent decisions and contact organizations that support people wiht disabilities, they ahve public power and acceess to media. For that matter, you could write a letter to you local newspaper. The choice is yours.
