I work as a tech support at one of Swedens largest companies. A customer calls in, identifies himself as a Research and Development customer (supposed to know everything, even more than me). And he says:
Customer: I am supposed to start using this new software.
Me: Ok, whats the name of the software?
Me: Come again?
Customer: Yeah Notepad, where do I find it?
Me (wondering if this is a prank): Umm.. Start > Programs > Acessories > Notepad.
Customer: Then what?
Me (doubting this is for real): You start to write?
Customer: And then?
Me (shaking my head): You save it...??
Customer: And how do I do that? I mean, if I click on Save, where will it be saved?
Me: Well, wherever you choose to save it; your desktop, my documents, your homeshare...
Customer: Ok and then?
Me: Well... you're done.
Customer: Thanks! (Hangs up)
I looked around to see if any of my co-workers were ducking behind their desk giggling but no... this was for real. I started to laugh my ass off, my manager had to come tell me to laugh more quietly :D And it still brings me much joy to remember this conversation, I doubt I will ever forget...
