I'm on a conference call, and every few minutes some guy on the call says "Hello? Hello?" like he's answering another call. We can all hear him in the background while others are speaking, and someone pointed out that we can hear someone saying "hello", yet it keeps happening. Then there's the loud mouth-breather that is obviously trying to impersonate Darth Vader

The chairperson has asked multiple times that those not speaking to put their phones on mute, yet we still hear Darth Vader and this idiot saying hello every couple of minutes.
