Well, what do you know? I got another email like
the one from a couple days ago with similar wording: different email address, different name given in the message, a couple unique words, but mostly says the same thing, asks for the same quantity of grilled chicken (150 chickens,) specifies the same date for the dad's birthday party, asks for some of the same information, in the same order... the name in the second email message looks suspiciously Nigerian.
So it really is some kind of scam!
