There's a breed of person that really, really wants to be seen to be courteous, even though the situation doesn't warrant it. Example 1: I'm a considerable distance from a door that the OCC is just going through, and it feels obliged to hold the door, despite having a 10 second wait before I get there. I consequently feel the need to speed up, as I am now inconveniencing the OCC, despite the fact I am just minding my own fucking business. Example 2: I'm waiting at a T junction and the only car approaching from either direction, driven my an OCC, flashes me to come out. It's fucking embarrassing - had the OCC just driven by, 2 seconds later I could have pulled out without any need for the OCC to become involved. Cunts. Well meaning, but nevertheless cunts.
