Client: I'd like to have internet at my home.
Me: Ok, let's talk about needful speed. What are you gonna use your connection for, simply checkin e-mail and some surfing in the net, or something that requires a faster connection type?
Me: Would you like to have dial-on connection or faster like ADSL?
Client: What are those?
Me: ...so, anyway, what kind of computer do you have?
Client: Oh, I don't have a computer, I just wanna use internet at home.
Me: Eh... what you are going to use for internet then?
Client: Err... do you mean I need a computer too? What next?
Me: ...hmh... (thinking: this conversation can serve no purpose anymore. Goodbye)
