How Many Hours A Day Do You Work ?

I work 10 hours plus per work day but I only have about 8 work days per month so I have lots of time to recuperate. The rest of the time I either have time off on layover or at home.
 
In my last responsibility (about to change) I'm paid to do 8 hours a day, 5 days a week but really I had to get serious for only about 4-5 hours a day centering around these two slots: 11.40-13.15 and 15.10-16.35.

The rest of the day, I just read random newspaper, go to boutiques opposite my workplace, read PF, etc.
 
I recently became the proud manager of a bar and cafe- owner doesn't care what I do, I however take my job seriously- I'm there from 7am til whenever! usually 10 hrs minimum, but only 5 days (although I do paperwork on weekends...)
