Seeing not a single person covering their mouth when they cough, including a fucking doctor, when there is a flu going around with a 100% death rate without medicine is probably the most frustrating thing I've seen in this series. The writing is so fucking bad that it looks like they specifically aim to cough on someone else. "I could cough to the side, into my shirt, or anywhere else away from you, but I'm going to look you dead in the eyes and cough directly into your fucking face". There has been some awful writing, but that shit really takes the cake for me.
