I saw a previous thread talking about payback day usage but it didn't completely answer my question. I know of an epic trick to use all of one's payback days by using a seinor friend. I have 5 days to use and someone willing to help out. How exactly do I execute this (spelled out for a dummy like me)? What kind of pickup limits do I need to be aware of and how to I (and the other person) avoid them? What pitfalls do I need to be aware of? Thanks for the help!
