It not politically incorrect, then "problematic" (https://assemblyofphantasms.com/2018/09/14/cheers-in-the-age-of-metoo/). For example, in the first half of Season 6 (https://en.wikipedia.org/wiki/Cheers_(season_6)), there's I believe, a running storyline (https://jacksonupperco.com/2016/02/23/the-ten-best-cheers-episodes-of-season-six/)involving Rebecca granting Sam permission to have sex with her because he did something for her. There's also that episode (https://cheers.fandom.com/wiki/A_Kiss_Is_Still_a_Kiss) where Mr. Drake initially mistakes Rebecca for being a lesbian because she worked on her car.
