ATLANTA -- The cola wars have degenerated to hand-to-hand combat.

A Pepsi employee allegedly assaulted a Coca-Cola employee at a Wal-Mart, Pennsylvania officials said.

Robert Koscho, 48, and Pepsi employee David Paulina, 42, are accused of bickering back and forth while making their deliveries at a White Township, Pa. Wal-Mart October 1. Officials told WTAE that as Koscho was leaving the store, Paulina attacked him giving him a black eye and broken nose.

The fight allegedly began over shelf space in the aisles of the store. Police also said the two are accused of trying to run each other over with pallets filled with soda.

Pepsi said they do not tolerate violence in the workplace and have fired Paulina as a result.

Police continue to investigate.
