I don’t know what world you to live in.
Of course I know that they all got home safely, because I see them again.
It is called socializing, you should try it sometimes, good for your mental health to have friends.
Over 30 years experience drink driving and I have never had even a minor accident, and I can not recall any of the thousands of people I have drank with over the years ever having an accident either.
The closest thing was my car getting smashed into when parked out the front of the pub by a sober driver coming around the corner too fast. I was in the pub and everyone heard the smash.
Bloody inconvenient that was. I had to pay for a taxi home but insurance reimbursed me.
