See, you say you are not insulting, but every word is arrogant, every comment absolutely correct. Here, let me chat for a moment. Yes, grammatically, both words you underlined are technically imperative in nature. That does not make them demands. He asked kindly, with pleases in both cases and a thank you to follow. I spoke to a doctor earlier this shift and asked for an order of medication. I don't remember the exact phrasing, but if I said, "Please give me something else for this woman's nausea. What I'm giving doesn't seem to help." Did I order the doctor around? Would he be offended that I, the nurse, commanded him to do something? Nope, because in spite of it's grammatical construction, I did not actually demand anything of him.

I am very pleased that you admit that it was grammatically a command.

You gave a bad analogy though. A very good analogy would be if you said to the doctor "Please don't treat this patient, you can treat the one over there instead". This one has all the elements: (1) asking doctor not to do his function (analogy to thread's function), (2) asking him to move to some other patient (analogy to moving to the other thread), and (3) making commands when you are in no position to do so.
