They are playing craps for money, gambling. Money comes in buying the chips. Color of the chips indicate value. The lady in the purple is Margret who is in her early 70s and the lady in the pink is Alice who is in her late 60s. They are from a small Midwestern town, not a big city. Cant tell who is winning, but they are completely free. Husbands cant tell them what to do, if they are still alive. They thought "lets do something very different before we get to old" so they went to Las Vegas. One day they were both sitting around thinking that they are both getting older and their friends are passing away. They needed something to look forward to physically and put a little spark in their lives, so they wanted to do something that they never would have done and over the top. They don't care what other people think because of their age. Cant tell who is winning because they are both equally happy. They could possibly be playing as a team and put their money together. They are playing against themselves shaking the dice. Anybody can come up to the table and place chips down. The red chips are 5, white are 10, and the green are 25. They are living life to the fullest getting experience. They could be friends or relatives, but have known each other for a long time. They have a lucky seven. Their dressing looks very identical which could indicate a close relationship and have a lot in common. Margret and Alice are going to get lucky in this game and then go to a show. They decided to do this game out on a whim on a way to a show and wanted to sample everything exciting in Las Vegas. In the end of the night they get to meet the star of the show. They are up for anything living their lives to the fullest. They might even end up going to Las Angeles/Hollywood.
