Should Lockergnomie Mike Nelson feel bad?

I run my own computer repair business. I am the only one locally that will actually go to people's home and fix their sick little babies. Mind you, I love what I do, but the attitude of some customers has left me thinking later I should have said this, or that to get my point across. A recent customer who had a partition virus, got a dump and reload, left me wishing I had thought of this to say or that, just not the right thing at the right time.
I was called back to their residents two days after I cleaned their computer with a new XP Home with SP2 installed. I had to put their IE explorer back to default settings so it was friendlier to the urls they were going to.
As I had her test it out to make sure it was doing what she expected, a pop-up showed up wanting to know if flash media could install on her banking site. I told her that was the SP2 in action and was normal. Next words out of her mouth, “well, what if I don't want SP2? I like the old way.” Knowing that Microsoft now doesn't give you much of a choice because of their policy change this month, I just matter of fact stated SP2 was for security, and she doesn't have a choice. SP2 is for her security and everyone else on the internet. After all, we would not want her computer spreading virus to other systems would we? I try to keep things simple for my customers as I have found over the years that simple, even if it is not 100% true, but it passes the 99% test, I am doing the customer a favor confusing them with long explanations. But I have to admit, in the back of my mind, I was thinking “Who the Hell does this person think she is?”
After I got home, I thought I should have told her that if she had a car that was being recalled to fix the wheels so they wouldn't fall off after a few thousand miles and endanger not only her life, but other cars around her, would not she take it in and get it fixed? I get disturbed that people just don't get it sometimes. I spend a few hours getting their computer fixed because of some action or lack of action on their part and I love doing it. I love helping people. Of course loving doing something and getting paid to do it is even better. But I do find myself getting irritated when people come up with this attitude I don't want to change the way I do things and I am going to do it my way whether it is right or not.
I am sure I am going to be called back to fix their computer again as I put Adaware, Spybot, Spyblaster, and a firewall on their computer when I redid it, but they are not going to keep them updated and run scans even if I put those first three in a Twice A Month Folder I created on their desktop. I realize that it just makes me more money, but attitudes of customers sometimes really leaves me shaking my head wondering why in the heck these people even bother with computers when they can't follow directions.
I guess I shouldn't complain, as it keeps my business going. But it is really hard for me to keep smiling sometimes.

I love helping people, too – and I always prefer giving the shorter explanation.
