I went to a wedding two weeks ago and the priest sat at our table for dinner. Then I got to thinking, am I supposed to invite Rev Jay to eat with us after our ceremony? I hadn't thought of it but now I don't know the etiquette on what to do- do I look stupid if we do invite him to stay since we don't know him or are we rude if we don't invite him. Also, do we tip him? I went on the etiquette board and the answer was wishwashy to me.
