An Internet friend of mine swears this is true, as it happened to him, in his office. He is the de facto computer repairman, only because he has seen the inside of one. One day, his boss asked him to do what he could to repair the cup-holder on the front of his personal PC. A cursory inspection revealed a CD-ROM tray warped beyond repair, and an expensive CD-ROM drive, useless.
To prove just how smart the people who work for McDonalds are I told my brother that I would order a cheeseburger without cheese to find out what the guy would say. He did just what I thought he would do, he called back to the grill for a cheeseburger with no cheese instead of handing me a burger off the warmer. The guy working the grill didn’t catch on either, because he wrapped it in a special wrapper instead of suggesting that he give me a regular hamburger.
I was working in a large Western National Park and a woman who was a notorious chain smoker came out of her office and lit up a cigarette. I said, “What are you up to?.” She took a long drag off of her cigarette and with smoke coming out of her mouth and nose said, “I just came out for a little fresh air”!
So, this chick that works in Tech Support with us, let’s call her Elaine, is doing training, and telling all the students what to do in case of a “one-zero” error. We pulled her aside to explain that that actually said I/O error (as in Input/Output) but she continued on with her teaching, explaining that it had to be a “one-zero” error, since computers communicate in binary code, so everything had to be either a 1 or a 0. I think its obvious who “1” and who is a “zero.” Duh!
