I've never seen anything like that happen during rush, but then, we didn't have any legacies come through while I was an active.
I especially like the post-dated check.
So what are you supposed to do with a gift from a PNM's mom or grandma? Return it? What if the PNM cuts you instead of the other way around?
As for the resume, sometimes you can suss out a lie by bringing it up in conversation. For example, if a PNM says she was on the track team in HS, you can ask her what events she ran and what her times were like - if she really has to stop and think, or if her event times are unrealistic, that would raise a red flag.
