If I went to pick up or make arrangements to pick up and the seller said I couldn't play it, Id tell him to pound sand too. That is just stupid.
I just wasted 6 hours of travel time, $400 in hotels/gas/food etc to look at a game. Thankfully he let me play it and it was riddled with problems.
Better safe than sorry, OP you are 100% correct in this situation. Thanks for the heads up.
