I get it. We all need a break some time. Especially if you work in retail. I've worked in retail and it can be very difficult. Sometimes every single employee's spirit will be shot for no apparent reason. It's like a collective sadness envelops the store. Those are the days when you all agree to close up shop. These employees must have had that same idea. "We'll say there's no power, then we can just chill." There are many flaws with that plan. The main one being that you left the lights on, dummies.
If you work any shit job, you have to take advantage of it as much as possible. I'm not saying every retail job is shit. There are many non-retail jobs that suck, and plenty of retain jobs that rule, but if yours does suck, take advantage at every moment you can.
