Thank goodness the Glorious Ice Cream Parlor serves its sundae sauce and ice cream in two separate dishes!   The new waitress put every item ordered by a party of four in front of the wrong person.   She served Jenny chocolate ice cream and fudge sauce; Ruth got mint ice cream and marshmallow sauce; Dave was served coffee ice cream and butterscotch sauce; and Martin got vanilla ice cream and chocolate sauce.

Although nobody got either item he or she had ordered, nobody got both the items ordered by anyone else.   After a brisk shuffle, when everything was where it belonged, the person sitting opposite Martin had the fudge sauce, the one on Dave's left had the chocolate ice cream, Ruth's right-hand neighbor had the coffee ice cream, and Jenny was sitting between the person who ordered butterscotch sauce, on her right, and the one who ordered vanilla ice cream, on her left.  

What had each person originally ordered?
