This is the ONLY stoned we are supposed to be at work.
Nowadays where I live that is automatic dismissal at any company. Even ten years ago could have a drink on lunch hour and still go back to work, but not any more.
I used to be on the recreation committee for my employer and used to throw huge Christmas parties with dinners and dance, and we would supply taxi chits for all employees. Most companies won’t even throw social events where alcohol will be consumed anymore, even if offsite and not on company time. So no, those days are over.
