I think they should be required to point out that a gratuity was already added for a large party when they bring you the bill. I know it already says it in small print on the menu but by the time the meal is over that's not on my mind. So many times I have double tipped and only realized it after the fact. It makes me mad. Yes, I know I should carefully read the bill but when we're out to dinner with all of our kids and grandkids, having a fun time, I just don't tear myself away from the conversation to review the bill. Again, I know it's my own fault but I think it's shady when the server doesn't mention it or circle it on the bill so that it stands out.
