Getting drunk at work

When is it not a bad idea? Obviously I know 99% of the time it is not a good idea to drink on the the job. But when is the 1% of the time its a good idea?
 
For me, its friday, on payday.

when collecting your items from your desk after being fired.

When you're the boss...

When it's one of your colleague's last days working with you. I don't mean getting drunk, but I went out for lunch with a few workers who were leaving the bank I worked in and got a pint or two in before heading back for the last 3 or 4 hours of work. Just don't make it a regular or noticeable thing.

Mad Men has inspired me to bring back the three martini lunch.  Unfortunately I can't afford martinis.  But when I can...

I'm doin it right now.

Valid point. 

It's OK to get drunk on the job when you work for Whiskey Media and you have a freakin' bar just 20 feet from your desk.

I used to drink all the time while I worked, ending up trashed at the end of my shift. 
 
Mind you I was a bartender at a nightclub, but thats clearly irrelevant.

We had a keg of rolling rock at work a couple weeks ago... Yep.

Occasionally after our Friday afternoon meeting we drink a bunch of beers and play twister in the office.

Just be careful when you're drunk at work, guys. It's super easy to spot someone who's had a few before work. I come from an office environment, so in some other lines of work, I can see you getting away with it, but at an office, where everything is all prim and proper and professional, a buzzed face is an easy catch. 
 
Also know that if someone knew you were drunk on the job, you'd never know and they'd never tell you.

When you work at an alcohol testing facility.

Uh. I work with machines and I'm only 18. So never is a good time to get drunk at work.

maybe when you are a bartender. people buying you drinks. 
 
when the boss is not there. last year when i worked we would sometimes sneak a drink. the place is in downtown city so there are bars and clubs there. we would drink during lunch break. sometimes the manager would come with us to lunch and drink. another time the guy bought some small shot type of drinks. i was buzzed. 
 
i work in another department now. in another department there is another guy who gets drunk. the other day the boss called him to do something. he didn't understand what he was talking bout. it was funny hearing him yell into the phone get the cart. the cart.

A glass of Scotch to go with some boring board meetings, that's when it's A-OK.

When your boss leaves for the day and your co-worker hands you a beer from the mini-fridge. Standard procedure, people. Didn't you read the terms & agreement?

Brewery, when you work at one.

When you're a viking.
