 CONT: Mary and Rhoda are sitting down at Marys dinner table eating  a salad while discussing the single life. The table is set with 2  plates and a salad bowl. When, all of a sudden in the middle of one  of Rhodas quips about her mother calling her "an old maid" when she  turned 21, the camera cuts to a wide shot and they are both drinking  coffee and holding mugs with no visible salad bowl or salad plates  in sight. This is a continuity issue because it happens right in the  middle of Rhodas sentence.
