Apologies for crap drawing and worse writing.
Nasty Man stopped in middle of road, double-parked, because he's waiting for lorry across the road move so he can have the lorry space. Another car, arrowed, female driver, is signalling to pull out.
I am behind NM, with a White van man behind.
Traffic builds up, cars in opposite direction squeezing through.
Lots of tooting (including from me). I suspect WVM is tooting at me rather than NM as WVM eventually squeezes past us both (but he's higher up with better visibility of road ahead).
NM gets out of car and shouts at me to pull around him (not much space, plus if he pulled on, there was a space to his left, meaning arrowed driver could pull out).
I stayed put until eventually he pulled into the space.
Who wbu? I could have just about pulled around him, but visibility was poor and I would have been forced into incoming traffic.
Also, woman with arrow would still have been stuck - and it was causing queues in both directions.
