Copy Machine?

User: "Can you help me with the copy machine?"
Me: "Yeah, sure - what seems to be the problem?"
User: "My copy card doesn't work for some reason"
Me: "Copy card? Can I see it please? ...Ah ha, this is for the library only.  You'll need to use your student ID for these copy machines"
User: "Huh?"
Me: *sigh* "These copiers are not run by the library, but instead use your printing allocation to copy"
User: "Well that doesn't help me, I paid a lot for this card, so it should work"
