I want extra time off work at lunch.
Why do you want extra time at lunch?
I need more time to play games and make my social network posts.
You're going to cause people problems if you don't get back to work when you're expected to. Go back to work after lunch at the agreed upon time.
I just want to do it for one day more so I can breath.
It would be bad to continue doing it even for one more day. People need you to be there when you should be.
