My dad, a wonderful and upstanding gentleman, who has never been in hospital until this incident.
Decided to walk the 5 min journey home from an 80th birthday party, with a good drink in him, slipped on black ice and snapped his ankle which required surgery.
He was knocked out lying in minus 1 temp and only came to after being found by my brother who dragged him into the car and to the house which was literary about 7 houses down the road and called an ambulance.
Dad was in shock, with a clearly disfigured ankle and was very very cold, it was actually really traumatizing for us all.
How would you determine if it was the ice or the drink that caused it or would you have a blanket rule of 1 drink and any accident means you are charged.
My mums friend, at my 21st party many years ago was standing and a bar staff tripped on one of the chairs, knocked into my mums friend who then fell, landed awkwardly and broke her wrist. She was drunk.
But would she be free from charges because someone else knocked into her that wasn't drunk, would she have fallen over so quickly has she not been drunk.
Can you imagine the amount of paperwork and investigating that would be needed, the costs would be unimaginable.
Your theory is basic level at best, dont just throw things out there without any thought or care at the consequences.
