Asking for chords is a pet peave of mine. You'll never be able to figure out songs by yourself if you keep doing it. But the thing is, you'll never be able to figure out songs by yourself if you dont ask that first time! If you're unfamiliar with matching chords to what you hear, when someone gives you the correct chords, you go "aha!"
Certain voicings, I'm still glad I can look up. I learn something new.
