You know what's really obnoxious? being repeatedly interrupted by clients asking you the question you are trying to answer. Here's a suggestion for anybody going to a doctor or expert of any kind - when they start trying to go through your lab results (or car engine print-out, or architectural blue-prints, or whatever) LET THEM TALK. When they get to the end of the section, ask questions if they missed anything. DO NOT interrupt them every 3 seconds to ask "but how is this all related" questions - THEY ARE GETTING THERE and you are just delaying it.
It is bad enough that on several occasions I have literally told clients to stop - this isn't just occasional questions, this is constant peppering of disconnected bits that don't allow me to finish a single thought, to the point that I start pointedly repeating EXACTLY the same 3-4 words several times until they stop interrupting me at exactly the same word, and if that fails, I tell them that the only way we are ever going to get anywhere is if they let me get through my spiel and then they can ask questions if I missed anything.
What makes people do this? I mean, if this was one person who was just seriously manic or overwhelmingly ADD or something, it'd be annoying but rare. Instead, I have similar encounters on an at least weekly, sometimes daily, basis with multiple clients. I don't get it.
In not entirely unrelated news, just got a call on the after hours line from a guy who interrupted every fucking sentence I said during the entire conversation, completely missed the repeating-start technique, and then didn't want me to call the hawk he was asking about a 'raptor' because that's "ominous"... it's just a little bird, and yeah, it has a hooked beak, and bit my friend 3 or 4 times, but "raptor" just sounds so mean.... *headdesk* This being toward the end of the conversation, I was pretty fed up with him anyway, and I pointed out that I don't care how big or not big it is, if he has a hawk of any type, it is by definition a raptor, that's what a raptor is, end topic. I did not say, but did think, "Also, your friend appears to be a fucking idiot and tell him to stop sticking his hand in or near the mouths of wild animals."
