Good observations! Was Mrs. Peck planning on taking the pastries over to her sister that night? She did put her coat on, but got caught up in the soap opera on TV. Which brings up a question: Isn't it kind of late for soap operas to be on TV? I mean, this was before the days of tape-delay, late night soaps (Dallas didn't air until the late 70's; it was the first night time soap since Peyton Place ended in 1969).
Could be, but the production value was obviously of the cheap, daytime soap opera style. Gotta love the cheesy soap opery dialogue, too: "If you're not cold and hard and tough enough to justify the faith and confidence of your patients, then you can hand me your stethoscope, Rocky." I always get a chuckle out of that scene, although I don't think that's what they were going for.
