You're at a junction (narrow roads, single lane each way). You see a mate that you want to talk to. Do you
a) wave to him
b) pull over and chat
or
c) stop at the junction and chat to him for 10 mins ignoring the 20 or so cars behind you that cannot get round you - blocking them completely until you decide to finish your (lengthy) conversation.
I have seen about 6 examples of (c) in the last couple of weeks. AIBU to be pissed off at the arogant fuckers?
