Stop in for a cup of coffee

Oh man I have a guy on another site I am trying to help out first he wants a rebuilt for a beater truck for a few years and havs a couple of core he would trade for some $ off, ok I get it. Then say I have a good one that is a core to me just for the cores to me and the ride of it to him. Wants to meet in a week since he will be in PA in a week. No sweat right? Well he is going to be two hours away and does not get why I wont do it just ship it all you will be out $30 tops. Wont do it and cant get why I wont meet him. WTF is wrong with people?????
