You may be a reference librarian if...

...if you've ever helped a homeless person print out a bank statement from the internet.

Especially if, in the process of making sure your printer's toner cartridge was shaken enough to not make pale streaks on every other document, you notice that it's not so much a statement as a receipt...a receipt for transferring $1,800 to a bank account in Nigeria belonging to someone whose name starts with "Prince."

Seriously, you have $1,800 to lose to an internet scam, but you keep all of your world belongings in a shopping cart with a tarp by the door of the library?

Then again, maybe you have $1,800 to lose BECAUSE you own a shopping cart full of stuff, and that's it.
