Yes but in this discussion it’s quickly become obvious that the listener is responsible for assuming good faith on the part of the questioner, because any phrasing can be interpreted as “I’m smart and you’re dumb.” Being professional is having the maturity to listen to answers when you ask questions.

Now, in the case of unsolicited advice, it may just be the questioner showing off. There’s no phrasing that will help make a person feel good that they were used to stroke someone’s ego.
