Links Added To the WordPress 3.1 Admin Bar do not appear for logged in subscribers

I followed the tutorial given here on how to customize Wordpress 3.1 Admin bar so I can add my own set of links relevant to my customer's experience:

I got it to work just fine and can see it when I am logged in as an admin but when I log in as a customer with subscriber level status, the links all disappear.

Can anyone help me with this?
