Scammed and looking for advice...

I was scammed last spring by an Ottawa U professor who reminded me of Mr. Bean. Here is the sequence of events:

1) I met Mr. Bean at a conference in a European country. Mr. Bean confesses that he has no cash, and can't even buy himself a cup of coffee because he can't get the bank people to understand him and for some reason he can't get a cash advance on his credit card.
2) Aggie, realizing that he is from Ottawa, the city in which she lives, hands over 50 Euros to Mr. Bean, along with her business card, saying, "Here. Borrow this. I know where you work."
3) Mr. Bean is grateful, and says how embarassing it is, but takes the money.
4) Aggie does not hear from Mr. Bean.
5) Aggie decides to email Mr. Bean in late August, reminding him that she is there.
6) He responds with photos of the conference, good wishes to Aggie, and says he is heading off to Paris for another conference.
7) Aggie responds with, "Have fun in Paris. Don't forget to bring your Euros this time!"
8) Mr. Bean doesn't respond.
9) Aggie's work colleague who also met Mr. Bean at the conference runs into him by chance on the Ottawa U. campus and says, "Hi. Remember me. Aggie's friend. Remember Aggie, the one who so generously bailed you out." He mutters, "Oh, yes." then rushes off.
10) Aggie's colleague recounts this chance meeting to Aggie. Aggie is now pissed off at this scamming bastard and sends another email, this time saying. "Ok, Mr. Bean. Write me the check for $80 and send it to this address"...
11) Mr. Bean responds curtly with a "Yes". No thank you. No Sorry. Nothing.
12) That exchange was a week and a half ago. No cheque has arrived.

So, blog readers. I am asking for your advice here. What are the next steps? What should Aggie do?
