You get out of work after a night shift, leaving the bar at 3- 4am in the morning, having to be back at the bar again the next day to open. Good old clopen.

In retail closing shifts often end between 9 and midnight and opening shifts start between 7 and 9 am. A clopen is a portmanteau of closing one night and then opening the next morning, thus having as little as eight hours to eat, sleep, and shower between shifts. Depending on the kind of retail and the hours involved, clopens can be a mild annoyance or a brutal test of human endurance.
I'd love to hang out tomorrow night, but I'm clopening, so I won't get home until midnight and then need to be up at six am~
