Interesting ritual-gizmo from Fresh Choice (an all-you-can-eat chain). At a buffet, how do you stop the staff from clearing your plates when you stand up to get more (or visit the restroom), especially if you dine alone? Here’s their solution, a two-sided laminated muffin card that you keep next to your plate.

I believe these are available as you arrive (at Fresh Choice, upon arrival you go through a cash line to pay and get your plate) although I didn’t see them. I saw the muffin cards around the restaurant as I walked back and forth to get more food.

While it does seem like a workable solution, it seems like a half-measure, shifting the service responsibility onto the customer. At a “nice” restaurant, the staff are attentive, but here you are doing self-service what with retrieving your own food, so maybe they figure why not give the diner another task to manage.
