I don't know about "calling in drunk". That would seem unlikely unless someone is really still drinking alcohol until early morning. Maybe nursing a hangover?
I've got a good story for "calling in drunk".
I used to be the overnight producer at a TV station. Hours 1a - 9a. When I got married, my coworkers wanted to throw me a bachelor party. My direct coworkers got off shift at 1p. So we scheduled the bachelor party to start at 1p on Thursday (my family was coming in on Friday, wedding on Sunday).
No problem. Best Man came and picked me up, went and met some coworkers at a club, and had some fun for a couple hours. Since we all rode together, we went back to the station around 6p so they could get in their cars. No problem, I was drunk, but had 7 hours before I had to be back in. They wouldn't let me out of the car.
The day shift was now off work and ALSO wanted to celebrate with me. So another group of us get together (including my boss), we go to another club, and I didn't buy a drink that night. Coworkers, including my boss, made sure I had a drink in my hand at all times. I finally begged off around 9-10p (had to be at work at 1a the next morning).
Best man gets me back to my apartment and I basically pass out in the bed. Fiancée gets there around midnight and tries to wake me up. I wake up, but couldn't move. I end up calling in saying I can't make it. The supervisor who took the call tried to convince me to come in. I couldn't. He arranges for me to swap with who was working Saturday morning.
After the wedding and honeymoon, I return, then am given a two day suspension for "calling in drunk". The morning weather guy (who was also at both bachelor parties) actually went on air still drunk. He got suspended also.
In my opinion, since everyone (except me) knew about the 2nd party AND my boss was buying me multiple drinks just hours before my shift starts, they should have already made plans to have someone cover my shift.
I ended staying with that employer for 29 more years.
