Doesn't matter if that cup is 5 weeks old and has nothing but water in it... walking in with a Sbucks cup shows that you literally have no time to make your own coffee at home!

Alternatively, you can always head out for an "Important meeting" (i.e. 10 minutes of Nandoo walk ) and get rained in dope ass cash rewards !
