Absolutely
Which is why the point about respecting other techs is, most of the time, impossible. I set up a brand new computer, new soft, test it at my lab and its 100% operative. I go to the client and set it up there. And, behold, Internet crawls slower than Windows Vista on a 286 with 2 Mb RAM. I get out my Linux troubleshooting disk - I don?t know crap about Linux, a friend set it up for me - I boot from it and run an MRTG against mit.edu (just because I like MIT) and I find there's an 80% loss on one of my client's ISP's routers. So I call their help desk and spend the next hour and a half talking to a guy who says the PC is having a configuration problem and wants me to go into Control Panel and check the keyboard layout. And when I mention MRTG and routers, they kinda reboot and begin again from zero. Yeah, sure I?ll respect them.
