I’m thinking a food tray (like at drive-in restaurants of yore) for each partner to hang on the other partner’s left shoulder. Height and personal preference would determine if the tray hangs on the near or far side of the shoulder. Left-one-handed consumption while waltzing or quickstepping would be a challenge, as all things worth trying once.

Picture a foxtrotting beau tête-à-tête whispering sweet nibbles into the ear of Mademoiselle as she cheek-to-cheek munches a salsa hors d'oeuvre, amid belle hops and garçons on roller-skates circulating to pour vin maison and scoop ice cream du jour.
