Well I went to work today, and emailed him letting him know I was super busy (honestly) but I did slip away for all of five minutes and met him by the elevators. He gave me the money "bundled" and I didn't check it until I was off (over an hour and a half later) found out he paid me $5 extra (which i had already told him I did not want/need). But the good thing was he wasn't as creepy as I thought in person. And he looked nothing like I thought but the good thing is, I feel much much better now that its over and I no longer have to keep in touch with him should I choose not to. Thanks for your advice everyone - i legitimately thought he could have been a serial killer!
