Discretion is the key word here. It might be a good idea to go to the bathroom and on the way back stop one of the wait staff or see a maitre d'. No need to be worked up or emotional. They are there to make your experience better. In the case where they can't reseat you, then you should let them know how your experience was ruined. If it's a good place, they'll take care of you. Taking the direct route is much more difficult.
