I detest when people use speakerphone for the sole reasons that a) they are too lazy to pick up the receiver, or b) they just think speakerphones are a pretty neat idea. If one has a legitimate excuse, such as a) a call involving more than two people, or b) no arms, I can see it. But using it just to use it? Never.

Particularly anoying is when someone uses their speakerphone to call someone quite literally three cubicles away, so everyone (namely, me) is subjected to not one voice, not two voices, but three voices coming at them -- two conversationalists and one speakerphone echoing everything a split second after I heard it the first time.

Three cubicles away. I mean, honestly.
