Service Delivery

This is the second I've gone to the Mukuru Parkview Corporate and the guys have been out for lunch and close the branch. When it first happened I understood that the lady was working alone and had no one to relieve her. But this second time there were two ladies and on their return one of the ladies proceeded to go on her computer and not serve anyone, even though there was a queue of people who'd been waiting for them who now had to be served by the one person working. Making you wonder why even have two terminals? Also since there are more of them, why not schedule it so that there's always someone available?
