I tried to book some seats at the local branch of a chain of cinemas through their web site. It wouldn't work, at least not in Firefox. I tried Safari too, with no greater success.
I fired off an e-mail, and received the following reply about 24 hours later, the interpolated comments being mine:
"Please accept my apologies for any lack of functionality you have encountered whilst using the xxx Website. I can appreciate your frustration as an Internet user that you would like to use your browser of choice. However I'm sure you can appreciate from our point of view that we want to make our website as readily available to the general public as possible. [And we don't want the money or patronage of anti-social misfits who refuse to worship at Bill Gates' altar-TR]
As a result it made sense to invest heavily into our web site to ensure immediate functionality with the world's most popular and well used [they forgot to say most insecure-TR] Web Browser "Microsoft Internet Explorer" [why the quotation marks?-TR]. A significant majority of the world's internet users have IE installed on their machine even if it is not their first choice of browser so the option to access the xxx Website through this medium is always on offer to the customer. [Microsoft announced back in 2003 that they would no longer develop IE for the Mac, the page on their site now saying "....as of January 31st, 2006, Internet Explorer for the Mac is no longer available for download from Microsoft. It is recommended that Macintosh users migrate to more recent web browsing technologies such as Apple's Safari"-TR]
However I am happy to inform you that xxx is investing time and effort into ensuring functionality across the many Web Browsers available to
Internet Users, hopefully including Netscape Navigator and other Gecko based Web Browsers such as Opera and MoZilla. [Why the bizarre capitalisation of nouns...was this written by a German speaker? And the illiterate use of hopefully...?-TR]"
