Jack of all Trades
I think most of us in the U.S. quote it as Jack of all trades, master of none. I try to keep in mind that most citizens of our fair country are quick on the draw when it comes to filing lawsuits and are careful of what we offer in terms of service. My wife has a client that has an older PC that's running slow and wanted to know if I could fix it. I told her to ask the client how old the system is. If it's more than five years old I told her to have her client to replace it. From my conversation with my wife, I picked up a vibe that it was probably a PC that was running Win 95/98 and that was manufactured in the mid-90's.
