Ah, no. Took me a couple of decades to learn to parse that, but, in fact, nope, it's not a solicitation for a preference, it's a direct command. Or, at least, it's been that every time someone has used that phrase at me.

I honestly don't hear requests phrased to me that way very often (I can't even think of a concrete instance).

Obviously, there are ways beyond the mere statement that can indicate whether it really was an open question or just a softly worded request (body language, tone, general context). I am by no means blind to such things.

However, it's important to distinguish when a particular usage of language is just wrong, regardless of its popularity. There are far to many ways of putting a request politely without blurring the intent or coming off as passive-aggressive.

I would be inclined to reply with the suggestion that they might begin to consider whether they might perhaps benefit from some assertiveness training.
