I did that one time.

Me and a few friends smoked it up and drank a shit load of beers until like 4 AM. Then I slept until like 10 and i had work at 11:30.

It was so bad. I was the most asshole BK employee they have ever had. They put me on register, and if some old dicks wanted a tendergrill garden salad(you have to punch like 6 buttons to get to the tendergrill), i'd be like "we're all out."
