On the new york routes (not yow to yyz) I have always been served free booze when asked.

As for the free headsets, I have seen them given out however when they see I already have a pair, (im usually wearing them) the fas have never had a problem giving me a free drink instead for the delay.

I have to disagree with yyzsd, what may be guidelines is not practice. I have seen fa's make a greater effort in customer service on the ny routes (no doubt due to competition, and premium fares being paid). I have also seen quite a few airsmiles being requested (by pax), including myself!
