Not on my commute exactly...
Just saw a cyclist giving both barrels to the driver of a John Lewis lorry outside the office (Southwark Street). I was inspecting the Borisbikes when she pulled up alongside the parked lorry across the road and started having a go. Couldn't quite work out what her beef was but it seemed to be something he'd done back down the road and she'd caught up with him when he stopped to make his delivery.
The driver looked pretty sheepish, so I suspect he knew he was in the wrong. Didn't seem too keen to apologise, though - he just wound up his window and gestured to her to go away but she wasn't having any of it, parked her bike against the front of his lorry and took down his details, and made it clear she would be reporting him to his boss.
Anyway, just wanted to say: Well done, that cyclist!
If you're reading this, I was going to cross the road to offer moral support but there was too much traffic and by the time it had cleared, you were on your way. And whatever it was the lorry driver had done to get you so upset, I hope your complaint is fruitful.
