A while back quite by accident I ran across a couple of GE promotional films on YouTube that featured Bette Davis. Both were made in the early 30's. The first one was only about a min. long and showed Bette and Ruth Donnelly doing dishes in Bette's new GE in counter dishwasher. The second one is about 4 mins long and this one has Bette entertaining a few Warner Bros. co workers in her new GE electric kitchen. I believe that they were both made at the same time. If I knew how I would try to post the links, but this is beyond my tech challenged capacity. I did however manage to find the shorter version by just doing a YouTube search for Bette Davis with dishwasher. By the way, I'm a real fan of TCM too, I watch it at least once everyday and have since it first went on the air. It's the best thing on TV! As far as the bowl scraping, I think that Mrs.Jones did scrap after a fashion, she just didn't use a rubber spatula. She was clearly well to do, so even during the Depression waste didn't seem to matter to her, my Grandparents would have been outraged at the waste.
