Here's a curious email I just received:
Hallo! My name is Wojciech Krajewski. I come from Poland. I'm collecting museum entry tickets. I would be very happy if I have got in my collection ticket from Yours. I hope that my favour won't be a problem for You and that you won't leave it without answer. I give my regards to you and thank you very much.
I'd really like to help this guy out. But what should I send him?
