HONOLULU -- A local businessman is accusing a U.S. Postal Service employee of tossing 20 cases of his company's juice out of the back of a delivery truck.

It allegedly happened Saturday during a delivery to Spray Liner Hawaii in Mapunapuna, which Randy Vasconcellos owns.

Vasconcellos showed KITV surveillance video of boxes flying out of the back of a U.S. Postal Service truck.

"I was very upset, very upset. I couldn't believe it," Vasconcellos.

The truck was delivering juice for Vasconcellos' other business.

He stepped out briefly when it arrived. When he came back, one of his employees told him what had happened. Vasconcellos then confronted the letter carrier.

"I asked him, 'Why did you throw my cases out of the truck?' And he said he didn't. He totally lied about it. And I said, 'You look up there. There's a camera there and if it shows that juice flying out of the truck, I got you.' And his face changed," Vasconcellos said.

Vasconcellos said that the carrier never admitted to anything, but that he did say one thing.

"He said, 'You didn't help me unload it,'" Vasconcellos said. "We bring in about 1,000 cases of juice a month. That's $8 a box, and for me to be treated that way, I was pretty upset."

"First of all, we want to apologize to Mr. Vasconcellos for the inconvenience caused by the carrier," U.S. Postal Service spokesman Duke Gonzales said.

On Monday, Frank Sato, Honolulu's postmaster went down to Vasconcellos' business to meet with him in person.

"He was very apologetic. He reviewed the tape with me and he said he would cover all damages," Vasconcellos said.

The carrier who chucked the boxes of juice out of his mail truck faces disciplinary actions.

"We'll be discussing with him the incident and if any disciplinary proceeding need to be held afterwards, we'll be take care of that at that time," Gonzales said.

"Our regular letter carriers, they do an excellent job. It's just a few bad apples that give them a bad name," Vaconcellos said.
