she might have been just doing her job and trying to protect you from a scam even though there really wasn't one. they have to take them seriously. I know there are at least a few people in my town that get taken advantage of like that, not for Nigerian scams but other scams, basically the same. Putting a hold on it wasn't necessary unless imo, unless you didn't make it clear that you were joking. But yeah, it actually happens though.
