I don't have a problem with this. But I really do if the service is bad. I usally tip 23-25 % or more. With the gratuity charge I feel like it's taking away from my privlege to tip. So the tip will often end up around 20% just because of this. The service I have had at multiple restaurant's with groups has always been good and have tipped very well ,then why the charge ? I can figure why. But does this hurt your tip's sometimes ?
