What we suggest is that the product is shipped in two separate pieces:
1) A stack of lids.
2) A bag stirs (straw with tiny spoon tip).
The restaurant worker would have the two stacks by the drive through window and simply assemble them before popping the top onto the container. The spoon snaps right into a hole on the underside of the stirring part of the lid. The spoon will be specially made to fit this device.
