Pay the marker. What kind of lowlife, bottom-feeding scumbag would make up a fake marker? I mean, lawyer jokes aside, this dude is supposed to be your friend, right? Pay it in public if you insist. But I would suggest that you: 1. Bring enough cash every time, 2. Sign your markers or otherwise remember who's holding them, pay that guy back asap and make sure you physically tear up the marker in the process. Markers are just a bad idea and remembering about money owed to friends/coworkers is just really messy.
