Helping patrons or helping scammers?

I got this message from a classmate of mine a couple of days ago. What would you have done? She’s looking forward to hearing the comments of others…

“this morning a lady brought in two papers she wanted me to fax. i try my best not to look at people’s faxes, ’cause it’s really none of my damn business, but i couldn’t help noticing that she wanted the information faxed to madrid, spain. besides, she was going on and on about this money she won. so i’m looking at it, and it’s this letter from the ‘international lottery commission’ asking this person to fax a copy of her driver’s license to two numbers so they can get started depositing $800,000 into an account for her. i’m thinking, ‘lady, you’re about as gullible as they come.’ here’s the question: what would you all have done? what would CLIS students have argued in class if this situation was presented to them? some would say, ‘you’re a librarian. what they’re doing is none of your business. yada yada yada.’ some would say that you should tell this patron the deal.”
