A couple months ago I managed to lose my driver's license (but not my whole wallet) on the way to the airport. Somewhat to my surprise, I didn't have a real issue with TSA. They gave me a very thorough screening but it wasn't really an issue.
However, when I got to the Travelodge at SFO, they REALLY didn't want to check me in even though I had a reservation in their system. The only way I could persuade them was to pay cash plus a security deposit and to let them make a copy of my work badge with photo. Had I not had that with me, I don't think they'd have let me check in.
