Can you imagine the ambulance response...
We are driving along on blue lights and sirens, traffic is heavy and we are on our way to a potentially life-threatening call.
From the side of the road we see a member of the public gesticulating angrily at us. He is shouting, swearing and indicating something to us.
He is angry because our sirens are so loud they are disrupting his mobile phone call.
Obviously a more important phone call than our emergency journey.
One member of this ambulance crew may well have made a rude hand signal at this pillock, I wouldn't like to say which one.
I happen to think it was justified.
