For many, cocktail functions provide the opportunity to network and meet new people. If attending a reception at which there are few if any tables, do not try to juggle handling your drink as well as a plate of food. Opt for one or the other. However, if handling food, particularly finger foods, hold the plate in your right hand in order to pick up your food with the left. In this way you will be able to switch the plate to your left hand if approached by someone, with the right one remaining clean you will be ready to shake hands.
