Reserved?

This may have been mentioned before, but I was watching Friends yesterday, and being that there were 3 eps on yesterday, I cant remember which one it was in, but I know it was either TOW Phoebe Runs, or TOW Ross Moves In. But anyways, there was a reserved sign on the napkin holder on the coffee table at Central Perk. Just wondering why that was there, because I noticed that in the next Central Perk scene, it was gone. Lemme know if you have any ideas. bye!

I've noticed it too, but I'm pretty sure I've noticed it somewhere else on that coffee table in other episodes.. though I can't suggest any to back my statement up right now ;)
