When I was doing tech support
Me: Can you start your Internet Explorer now
Customer: Ugh, Internet what...
Me: The Big Blue E on your desktop
Customer: I don't have that!!!
Me: The Big Green N ????
Customer: Oh, Thanks it's working again
Another one
A couple of years back I helped a really old guy with his ADSL connection when I worked for an ISP (we are talking 1999-2000 here - broadband was not yet a big thing over here). After reinstalling some drivers and the PPPoe software everything seems to work again. I could ping his IP but to be sure I just asked him to surf around. He starts IE and gets his homepage. So I ask him to surf to another webpage. Then we had this conversation.
Customer:"What do you mean with going to another webpage"
Me: "Well Sir, you have like this space on top where you can type, it says something like
http://www........
Customer: "Oh yes I see it"
Me: "Can you change that for me to
http://www.intel.com and then just hit Enter"
Customer:"Oh my god -- I have an other page now, it's all blue and different from the Internet[TM]"
Me: Yes isn't it wonderfull -- Have a nice day sir (click)
This was the first time that he saw something else then his home page. That old fart was convinced that his home page WAS the internet and he was using a nice 1 megabit adsl connection to surf to this homepage every day for the last year.
Doing helpdesk is more like kindergarten.
