a grapefruit tale

Back in Syracuse for a few days. The Jennifer, The Michael, and I went to good ol' Wegmans, which I have to say that I do indeed envy at this point because of its gargantuan selection. It was a dark and stormy night. Late, around 11:00. We were cruising the produce aisle, Michael in charge of the broccoli, Jen and I in charge of the citrus fruit. Much of the produce had been picked over. On the grapefruit display, all of the big ol' yellow spheres were high up, and on the bottom rows, there was one cellophane package of a sliced open grapefruit. Said cellophane package looked quite yummy, so Jen picked it up and put in the cart.

We strolled along through Weggie's, picking up everything but the one thing we actually went to the store for (cereal), and happily made our way to the checkout. Jen and I were busily blabbing as we put the bags in the cart. The checker stopped, confused. She asked Jen if she was sure she really wanted the cellophane-wrapped grapefruit. Jen said, "What, is it open?" Checker says no and looks around for the manager. She shows Jen the sticker on the bottom of the grapefruit package that clearly says, in capital letters, DISPLAY ONLY. Jen tried to buy the display grapefruit which had been sitting on the shelf for how long, even the manager didn't know.

My question is, for whom was the display intended? Who really needs a visual of the inside of a grapefruit as an incentive to purchase said grapefruit?
