We hear about the freakouts, the verbal lashings, the accidents and many more.
But what are some small things, things that have little consequence but are still infuriating or that drive you up the wall?
Here are some examples of my own:

1. People flocking to the metro doors without leaving proper space for people to leave.
2. Hearing the same 3 questions at work every time.
3. People walking slow enough to pass but not letting you.
