1. whenever there is a scene at night. Someone entering their own home....a murderer etc waiting inside for them hiding.....and the house owner walks in and walks around the house putting the coat away etc and never turning on a light - is it electric that pricey
2. Someone being chased by kidnappers/murderers they're in a busy shopping 'mall' or town centre and they run to the nearest darkest alleyway so no one can witness them being kidnapped/murdered or help.
3. People making people hot drinks tea coffee etc and the cup/mug never has any more than 1/4 full by the way they take sips from it.....
Something that grunches me also when people go for lunch /dinner have 2 bites and leave the rest of the food.
