Actually, there is. There's an episode where June couldn't do the shopping, and Rita was bitching at her about it ("I have to do your work as well as my own"). The Marthas you see in Loaves and Fishes aren't there because they want to be. Shopping isn't part of their usual job description. They're there because either the household is between handmaids, or the handmaid can't do it that day for whatever reason.Well...there's no evidence of that in the series. Sure, it happened in the book but that's not inherently true for the series until it actually happens in the series.
I've read the novel more times than I can remember - certainly over a dozen. I've seen the movie many times. I've seen many of the episodes twice, plus multiple viewings of various clips on YouTube channels where the series is reviewed, dissected, and discussed. Yes, the movie matters because the same people hold the rights to both the movie and TV series - and I've noticed that some of the series dialogue is word-for-word identical to the movie. FFS, some of the music in the Luke-centric episode in season 1 was very close to some of the movie music.
So I do know what I'm talking about, thankyouverymuch.
