Did you ever consider going to an Odeon cinema in the UK? Well, ... their main web site does not work at all (quite literally) with the two main Apple Mac browers Safari and Firefox, which is quite an achievement considering they are more standards compliant than, for example, Microsoft Internet Explorer. Also, given the many security exploits that MSIE is vulnerable to, many people are switching away from it to more secure browser versions.
So, when a public-spirited accessibility hacker came along and built an accessible, easy-to-use and legal front end to the Odeon site (their site is so poor it contravenes the Disability Discrimimation Act), you would think they would show some gratitude. But no, Odeon's Marketing Director Luke Vetere would prefer a significant percentage of his potential customer base seeing nothing at all rather than an accessible version of his Web site that they do not control.

This story has to just blow over, surely? I use the accessible rail timetables on Matthew Somerville's site as a preference over network rail - heaven forfend that they get caught up in this as well.
Also, it's not just about the 15% - the accessible versions of Odeon, rail, Hutton, etc are just more usable, improving my customer experience with all of these services.
So I'm sure Odeon will back off once they get some feedback. Let's hope they buy the design!
