It's tough to decide on this award, but here's a candidate-- call him Joe.
Joe always has about 80 items on order. He discovered 100 is the limit. Frequently he "accidently" hits the "delete all holds" button. Then Bernice has to call the help desk for III to restore the list. However, his place in line is lost.
Also, he believes staff have an "unfair advantage" on ordering the new DVDs. He thinks they are cataloged in the client first before they are displayed in the web opac, which, of course, isn't true.
