Big ticket site showing directory structure

I mean how stupid can people get ?

www.rialtoticketing.com would have employed a big company or would have inhouse developers to design their ticketing system. How could they leave a directory listing visible to public ?


http://www.rialtoticketing.com/app/rialto/ lets you browse their directory and read the code !!!! Amazing thing is that they do not have any contact address on their website. I am emailing their webmaster@riatoticketing.com anyway.

I am attaching an image to show that the directory was accessible at this point of time.
