This took place back at the end of the eighties. (The 1980s, that is; I’m not THAT old.)
I was a technical service representative for a copier company that actually invented the xerographic process. Our team was comprised of sixteen people covering a large area, so most of us were “out of town” from the area office.
We were in an all-hands team meeting. The team leader was well into his presentation when the receptionist knocked on the door.
Receptionist: “Sorry to interrupt you, but there’s someone at the front desk asking to see you, and he says that it’s very important.”
Leader: “Who is it?”
Receptionist: “Never seen him before, and he won’t tell me his name. He says he’ll only speak to the… most important person in the office.”
The leader assistant got up.
Leader Assistant: *With a smile* “Go on, [Leader]. I’ll see what’s up… on your behalf.”
He was gone for a few minutes. He walked back in, smiling hard, obviously repressing a laugh, and took back his place, not wanting to interrupt the leader. But [Leader] stopped anyway, like all of us, puzzled by it.
Leader: “So?”
Leader Assistant: “Oh, just some weird-looking guy who said that he had found a way to print in white on any colored paper. He wanted to tell me his discovery and make sure we put his name down so he would be credited for it when we will eventually market the idea, telling everyone he was the first to think of it.”
Leader: “What was his idea?”
Leader Assistant: “To reverse the voltage of the process. That would create white text instead of black text.”
We all laughed. Apparently, that guy had never researched how the process worked; toner (dry ink) does the actual “printing”.
Tech #1: “What did you say to him?”
Leader Assistant: “I didn’t have time to waste to explain how the xerographic process works, so I took his name and information and told him that if we ever go on with that idea, I’ll let him know and he’ll have full credit. [Receptionist] had to turn away so as not to laugh in his face.”
Tech #2: “And you threw his information in the trashcan as soon as he left?”
Leader Assistant: “Oh, no, I have it right here in my pocket. I want to put it down on our ‘do not hire’ list.”
