Weddings: How To Handle People Who Assume Their Invitation Is A Plus One When It Isn't

How do I handle people who assume their invitation is 'plus one' when it isn't?

It puts you in a difficult position when people assuming their wedding invitation has a plus one, but I think it's very important for you to be honest with them. Say, "Unfortunately you are not able to have a guest." Just remember it's your wedding and you should have the people there that you want to be there.
