People make me sad.

Customer: I'd like to get a price on a piece of equipment on your site.

Me: Do you have the ad number?

Customer: Ad number?

Me: Yes.

Customer: Uhm. I have an A.D. number.

Me: Yes sir. That would be the ad number.

While we're at it.. when did saying Good-bye on the phone become passe?

Come on, people (especially people on cell phones, because there is no audible 'click' to tell you that you've been hung up on) throw me a friggin' bone and say something, anything, definitive to let me know you're hanging up, so I don't sit there on the phone like a jackass because I don't want to inadvertantly hang up on YOU.
