Thank you Pat Coffey
Wasn't a religious follower of "The Dick Van Dyke" show reruns but couldn't imagine Laura Petrie not having a washer and dryer in her suburban New Rochelle home. I mean can you picture Mrs. Robert Petrie in all her bouffant coiffured glory going to a laundromat? Pedal pushers nor not....*LOL*
Like Samantha Stephens and much of the 1950's 1960's sitcom moms, Laura Petrie was pretty well off, at least solidly middle class. She had furs, a great wardrobe for going into town for shopping, dinner with her husband's clients, shows and what not so you can't tell me she was out back with two wash tubs and a mangle.
Did TDVDS have an appliance corporate sponsor like GM/Frigidaire for Bewitched? That could be why we never saw such things prominently placed in Laura Petrie's kitchen.
