A lady wearing a blue dress and earrings, is sitting at a table with a napkin in her hand and her elbow on the table.
The female is waiting for her order.
The lady does not have to be waiting for an order just because she is sitting at a table with a napkin.  The lady could be sitting or waiting to order.
Just because a lady is sitting at a table does not mean she is waiting for her order.
Not everyone that sits at a table is waiting for her order.
