You do have to wonder some days...
I've just been checking the online support for our library management system. It's one of those that "invites" you to check out the resolutions of existing calls before logging one afresh, which lets me see this gem:
Please re-open log #1575. This problem is not resolved.
I wonder what percentage of problems logged on this system are really just people saying: "Don't close this call, this problem is not resolved?" And I wonder what's best: "95% of our logged problems are closed within a day" or "90% of our problems generate more than two complaints from customers."
