Why were tomatoes taken off the shelves during a recent Costco visit by Sarah Palin?

Evidently the store managers were worried about any renegade costumers pelting Palin with tomatoes.

“It turns out that Palin had been pelted with a tomato at an earlier stop on her book tour and the management at the Costco was determined it wouldn’t happen here…” a source reported.

These were smart preventative steps taken by Costco to ensure the integrity of the behavior that occurs within their store.
