The problem for me isn't exactly that it's phrased as a question, but that the question isn't the correct one, especially if it's something vaguely unpleasant.
If the question is, "Would you please step on the scales?" The answer is going to be, "Of course."
If the question is, "Would you like to step on the scales?" The answer is going to be, "Not really."
I guess I could some it up is, if you want me to do something, ask me to do it. Don't ask me how I feel about doing it. They aren't the same thing.
I recently had someone get super upset with me for this at work.
I don't 'ask' people to follow the (posted--clearly and repeatedly!) rules because I find it results in arguments. (I make sure there's a 'please' and I begin with "I'm sorry but..."--the first time. The second time, I'm very direct)
"You'll need to put your drink away, we're not allowed to have beverages in the lab" was met with much grousing.
ANd later the student coming to tell me how incredibly rude I was and how upset he was that I wasn't respecting him by telling him what to do, it was treating them as children. I should ASK him to follow the rules.
I'm afraid I wasn't as patient as normal and I told him that I'm always polite but that if I have to repeat myself more than once, because people choose not to read the eight posted signs stating that rule clearly, I don't ask them because it's not optional.
But I did tell him that he was welcome to report his problem with my behavior to my boss. (which, let me say, I would LOVE to see. LOVE. My boss is awesomely wonderful at politely ripping someone to tiny bits and making them feel like a heel. To be a fly on the wall at those moments
