The classical boss-subordinate relationship is ask (order) down, guess up.
It's more complicated. Ask/tell is simpler, faster, and more efficient so in the workplace (where status and power relationships are largely formalized) it tends to dominate anyway.
Also, as anecdata, I know a girl who is a very pronounced Hint/Guess person, but she's a manager and has underlings. She quite successfully manages them mostly on the Hint/Guess basis (within reason, of course).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
