You can't win, but what's best practice?!
So, one day, I'm cycling along a designated pedestrian/ cycle lane and there are people ambling along in front of me, occupying the full width of the lane. I tinkle the bell, they nearly jump out of their skin, turn round and tell me there's no need to ring my bell at them. I smile politely and tear off. And today, I'm on my way home, with another couple walking right up the centre of the path, I try to gently thread my way around them and, just as I pass, the woman shouts 'you should ring your horn' (we'll leave aside for the moment the odd concept of ringing a horn). I suppose, legally, the bell needs to be rung at the risk of causing a heart attack?
