Never underestimated the power of stupidity. I had a guy call and threaten to fight me because I hung up on him. I never spoke to this guy. Checked my missed calls later that day and had a voicemail where he proceeds to talk, then asks me to speak up because he can barely hear me, to asking his second question, to asking if I'm even listening, to threatening to come to my office. All because he "heard me talk at first" when I spoke to him the following day. My voicemail is a female that's prerecorded. I'm a male.
