Should takeaway packaging be in the still and the clip of the dish?

No, if the menu dish is not the pack. It only comes in when what people order is that box, and then still and clip are the open box with the same contents. Ask whether the dish is sold at the table or in the box. In the sierra the reel is the bag and the menu shows the table dish. If it comes in, still and clip are of the box, not of the dining-room plate.
