When the last check on a table settles, the table turns amber on the map: 🧹 needs cleaning. The chairs take the same colour. On the host stand the lane reads 🧹 Clean me.
Tap the table when it is clean. It goes back to empty, the lane goes ✨ Ready, and the host can seat it. Cleaning outranks everything else the tile could say.
