If the majority of people in the office saw it, I understand. My issue was with 2 people in my office that watched 13 hours of House of Cards the weekend it came out.... most people don't have time for that so loudly discussing it in the office is messed up.
Also folks that aren't even on the current season should be used to avoiding show conversations. The convos and analysis are why I finally had to catch up on Breaking Bad and Game of Thrones. It sucks seeing a new (to you) episode and having nobody to talk about it with because everybody else is a season ahead.
