SAN DIEGO -- Just before Thanksgiving, delivery truck drivers pulled the "silver bullet" on Vons, Ralphs and Albertsons. They decided to honor the picket line and stop distributing to the supermarket chains involved in the grocery strike.

The on-again-off-again negotiations are back on and the Teamsters' actions could play a role.

How are the grocery shelves stacking up? The Teamsters predicted the grocery supplies would shrivel up, but have they?

"Each day, you're not sure what you're going to see, in terms of selection," said one shopper.

So, 10News decided to investigate the situation. They took a hidden camera and visited a Ralphs located downtown. A trip down the produce aisle revealed plenty of product. The story was the same for most other aisles, including baked goods and cereals.

But it wasn't quite enough when it came to some other foods.

If you're looking for certain beans, it could be a little tough. One of the frozen dinner sections looked barren. The deli appeared alright except for one empty case.

As for the slimmest pickings? Dairy and eggs were hit or miss.

One shopper never found the cottage cheese she wanted.

"It's a pain in the butt. It's getting old," one shopper told 10News.

The supermarket chains hired replacement truck drivers, and pre-stocked for the Thanksgiving holiday. But now some of that stock appears to be a little thin.

The Teamsters said their decision to honor the picket line has hurt the chains, but admit the pain is not dramatic.

Phil Saal, from the San Diego Teamsters, said, "The distribution has dried up to a degree, not as much as we would like, but to a degree."

Ralphs' officials told 10News they hired more than 400 replacement drivers and expect their stores to be well-stocked come Christmas time.
