1. Shell game
Summer crowds often mean long waits for food at popular waterfront destinations. At The Dock House, a laid-back seafood shack in Sag Harbor, N.Y., customers order their lobster rolls and fried clams at the counter, then step aside to wait until they’re ready. But instead of giving guests an annoying buzzer or sending a text as a ready alert, Dock House hands out small shells painted with a number surrounded by local motifs and the restaurant's name. The shells build brand awareness and are a conversation piece that made the time pass quickly while waiting for my number to be called.
