function drink(Promise, friend, pints){
  var count = 0;
  
  var promises = pints.map(function(pint){
    return friend
    .drink()
    .then(increaseCount)
    .catch(reject);
  });

  return Promise.all(promises)
  .then(congrats);

  function increaseCount(){
    count ++;
  }

  function reject(){
    return Promise.reject('Damn ' + friend.name + '! You stopped after ' + count + ' pints!');
  }

  function congrats(){
    return "Congratulation to " + friend.name + "! You drank " + pints.length + ' pints! Hura!'
  }
}

@Zae means the function drink you wrote wasn't returning a promise.
@neolectron Totally agree on that, i will next time, thanks for sharing.
@evannieuwburg agree on that too, would be nice. We'll think about it, see if it could be easily integrated for the next release.

Thanks a lot guys for your feedback!
