I am not really up to dealing with the harsh cynicism and assumptions of uselessness of our work with someone who leaves as soon as possible. Doesn't mean I don't like going home early. I do... But if your goal is to clock in at 8:30 and exit at 5:01, just to do the bare minimum, I can't jibe with that. I've worked with people like that... and I don't want to do it again.
Regards, pity, etc.
Pity? I pity you. Sad, Sad life when work is all you've got.
I would say that a motivated person is okay with staying 5-20 minutes late occasionally when trying to get something done that they care about.
