That’s a poor attitude, times have changed, I’ve 2 young kids and a wife and work away half the year.
I’m not saying rush but don’t go at a snails pace either, your not on the PGA tour.
So you think getting off the course after 18 holes 10 minutes early will make all the difference ? I suggest you've taken up the wrong sport if you are in such a hurry to get back to your wife and kids, may I suggest you take up football, couple of hours max from getting changed, playing and getting changed again, sorted.
