Corrected entry: Chrissy grabs an ashtray and lighter from the living room table to give to the old man, when none of them smoke.
Corrected entry: When Jack is complaining about Mr. Furley's shoddy plumbing, he demonstrates the sink functions to Janet and Chrissy by turning on and off the water faucets. However, after he turns off the faucets, he demonstrates the dish rinser, which works despite the fact that he never turned either of the faucets back on.
Correction: The plumbing was not working properly. This is pretty much what shoddy means.
Correction: Not uncommon, certainly at that time, for households to have them around for guests. I don't smoke but kept an ashtray for visitors who did.
