I'm not misinterpreting your posts. It's the characters, the speech.
For Supremes, coming up to someone, giving them a short bow and saying, "We need your help, in any way possible, oh great one!" would be considered extremely disrespectful.
However, if someone were to come up to them, and do this:
They come up to the Supreme, bow from the waist for a moderate period of time, and allow for the Supreme to bow back. Whoever bows first is showing greeting to the person, while bowing deeper than the other is a gesture of respect or admiration.
Once the bowing is done, the person who approached would say,
"Greetings, [honorific title, or name, depending on situation]. I have a request for [that one individual, his clan, his family, his branch of government, military, etc., or species-nation in general] to consider."
Then the Supreme would hesitate for a moment, and respond with something along the lines of, "I'm listening."
And then the person requesting something would go on, laying out what they are requesting, and then a preemptive offering of some kind, whether 10 bars of gold, or a chocolate bar, and then a payment after that. If the payment has yet to be arranged, one says just that.
That is Supremes' social way of requesting something from someone. Knowing that after I just put it in OOC, would, of course, be considered cheating. You'd have to negotiate a deal for a diplomat to stay behind and learn the Supreme ways in order to communicate and negotiate properly with them.
