I deal with customers like him all the time. They know nothing whatsoever about computers, but they're so sure they know what the problem is and are totally happy to think they should tell me how to fix it. ... FREE OF CHARGE.
Dipped my toes into that water. Thats why I steer clear of being a computer builder/ fixit fag.
Don't know what it is with some people, they want you to build/sell them a PC; then expect you to be free
tech support for life.
Then you have some small business owners who are having PC problems they can't solve, thats causing real problems in the way they conduct business. You solve their problem, they say they are happy, and expect a bill that won't pay for a Happy Meal and beer. However if you ask an accountant to do your taxes once, or janitorial service to clean your place of business once; as a means of barter for your services. The expression on their face... its as if you said to them, while holding a shot gun "You gotta purdy mouth, boi!"
