Does this want to be part of the `if` statement above? So if you either already have the cookie or if there is another bar visible you don't try and show the survey bar? At the moment you could never see the bar ever if it tries to show you the bar while the cookie one is present.

So it would be: 

    if (getCookie(userSatisfaction.cookieNameTakenSurvey) === "true" || userSatisfaction.otherNotificationVisible()) {
      return;
    }
