Completely agree with the packing a suitcase to storm off. It makes no sense what they put in it. It's always open the wardrobe and scoop out massive armful of quite "dressy" clothes still on hangers, dump in case, zip case and leave
Whereas in reality what would you really need? Pants, socks, hoodies, jeans, wash bag, make up, work laptop, chargers, contact lenses etc. What use is a smart suit or evening dress when you're off to sleep on your mate's sofa or whatever.
No one ever doomscrolling on their phone. I do appreciate this wouldn't help the plot though.
Police speaking to a witness who mentions something surprising. Rather than take all the relevant details they immediately get up and rush off.
In soaps the wedding outfits and fancy dress are always far too perfect/expensive for people supposedly living on minimum wage.
Police dramas again (also hospitals). You see the staff arrive in the cars at the start of the shift. Then after work they go to the pub and get trollied. Do the cars teleport themselves home?
I also agree with the poster who said lack of continuity about character birthdays etc. I notice this because I am on the spectrum and birthdays stick in my head to an embarrassing degree. On Eastenders Cindy's birthday was 10th May. For the first couple of years after she left Ian he moped around the square on 10th May remembering Cindy on her birthday. The following year he got married to Laura, on 10th May!
Also in Frozen Elsa's coronation is meant to be on her coming of age birthday and it is clearly late Spring and the kids are all dancing around maypoles. But according to her wiki fandom page her birthday is listed as 30 December. (I know this seems really sad but my daughter was a massive Frozen fan and asked me to find out Elsa's birthday because she hoped it would be 1st May like hers!)
