I have some experience of when accessibility was introduced into the retail sector. No one disputes that disabled people should have a right to equal accessibility, and that was implemented in the Disability Discrimination Act 1995. However, no one bales out private companies, and they had to consider carefully how to implement the provisions. Better off companies could bring in builders to provide a Rolls-Royce version, but great ingenuity was applied and disability groups and interested parties were helpful. I know from experience that getting disability groups to discuss how to improve accessibility was very successful. It was also good business since, if a shop is more accessible, it is available to more customers.
