Queue view-permission on "New ticket" for non-privileged users


I have several customers(which is the group of non-privileged users) and
want to set different queues for each customers.
However,I found that when those non-privileged user try to create on “New
ticket” button of the dashboard,the user could see every queues on the
service while the belonged group is not on the watcher of the queues.

I know that if the user is privileged then I can control the rights of
viewing queues.

Does anyone know how to control the rights of viewing queues for the
non-privileged users?
