You know how it goes. You have insomnia, can't fall asleep and hence get yourself a night shift to fill the time. You give them your extra eight hours, and they give you money. Cashback.
We all had this grand idea before - if we sleep less, we can actually gain more time to do other stuff (be it work or play). Yes, just like the protagonist in 'Cashback'. But the show really fails to mention the consequences of not sleeping at night, screwing your biological clock and not getting the proper rest that a normal human being requires.
Today, I gained an extra 5 hours from the night, slept at 7am and I woke up at 2pm. Ate lunch, took a nap at 3pm and woke up later for dinner at 7pm. After dinner, I slept (again) till 10pm to get supper. It seems like for every hour I gained at night, I had to spend 2 hours resting in the day. It's definitely more Payback than Cashback.
