A grocery store in Seattle’s Chinatown-International District says it is losing customers, seeing sales decline and fielding angry calls after a viral social media video accused the business of participating in food stamp fraud.

The operations manager of Lam’s Seafood Asian Market, a fixture in the Chinatown-International District that has operated for more than three decades, said the backlash has been unlike anything the business has experienced before.

“We had people calling and cursing us over the phone, saying we’re cheating customers,” said Teizi Mersai, the market’s operations manager.

Mersai said the fallout quickly extended beyond social media.

“The worst thing that really hurt is when an actual customer calls and says, ‘I’ve shopped with you guys for years. I’m never coming back,’” Mersai said. “Those are the ones that really sting.”

Mersai said revenue declined roughly 8% to 10% in the days following the video’s release and that the store saw a noticeable drop in customer traffic.

The controversy stems from a viral video created by conservative social media personality and self-described independent journalist Nick Shirley. In the video, Shirley purchases food stamps, also known as an EBT card, from a woman on the street before accompanying her to Lam’s Seafood Asian Market, where he alleges the store participated in a food stamp trafficking scheme.

At the center of the dispute is a transaction Shirley portrayed as a customer paying roughly $120 for a single can of luncheon meat and another food item.

But a closer look at the video tells a different story, according to Mersai.

The register screen visible in Shirley’s own footage shows the customer was being charged for an entire case containing 24 cans of luncheon meat, not a single can. The woman can also be heard speaking Vietnamese with the cashier and requesting a full case before the purchase is completed.

Mersai says those details were left out of the video’s portrayal of the transaction and helped fuel public outrage against the store.

Following the video’s release, Shirley tagged the FBI, Department of Justice and White House on social media, calling for Lam’s Seafood to be investigated and shut down.

The store later posted its own social media response disputing the allegations.
