Yeah at work one time...

I was working a slave shift (12+ hours), and I really needed to get stoned and keep morale up, so I went into our freezer where I ussually smoke (big freezer... many places to hide behind and shit), and I went to my ussual spot next to an exhaust fan that blew outside. I started getting stoned but I didn't realize that another employee was back their smoking already! Funny shit, he was new so I warned him who smokes and who doesnt in the kitchen that day.
