It's not really an issue of being lazy or practical. If you honestly dislike doing something, who wouldn't pay a little extra to not have to mess with it? And if its a money issue, the woman can spend her money as she sees fit. I'm more than capable of changing the oil and doing a tuneup on my truck, but its so much easier and quicker to pay someone else to do it. Frees me up to do other stuff too.
