[Drama] Starbucks Korea just fired its CEO over the worst marketing disaster in recent history (“Tank Day” on May 18)

TL;DR: Starbucks Korea ran a "Tank Day" tumbler promotion on the memorial day of a tragic 1980 democratic uprising (where military tanks were used to crush civilians).

They also used a slogan referencing a notorious 1987 police torture cover-up.

The backlash was nuclear, the South Korean President publicly condemned them, and the Shinsegae Group Chairman fired the Starbucks Korea CEO on the exact same day.

​

The Background (Context for Non-Koreans)

To understand how bad this is, you need to know about May 18th (5.18). On May 18, 1980, the military dictatorship in South Korea sent paratroopers and tanks into the city of Gwangju to violently crush a pro-democracy movement. Hundreds of civilians were killed.

It is one of the most solemn and politically sensitive memorial days in the country.

​The Incident

On May 18, 2026, Starbucks Korea (which is locally operated by the retail giant Shinsegae/Emart) launched a promotion for their new "Tank" tumbler series.

They proudly displayed the date "5/18" right next to the slogan "Tank Day".

If that wasn't enough, they added another slogan: "Thwack on the desk!"

This is a highly offensive reference to a notorious 1987 incident where the police tortured a student activist to death and tried to cover it up by claiming they just "slapped the desk with a thwack, and he died of a heart attack."

​The Fallout

The internet exploded. People couldn't believe a massive global brand could have zero internal screening to prevent combining two of the darkest moments in Korean modern history into a tumbler ad.

​Living right here in Gwangju, I can tell you the mood is absolutely furious.

The Gwangju Mayor instantly banned the use of Starbucks gift cards at any city-hosted events.

Furthermore, President Lee Jae Myung took to Twitter (X) to condemn Starbucks, calling it "inhumane, bottom-feeding behavior" that mocked the blood-soaked struggle of democracy activists.

​The Corporate Panic & Current Drama

As someone who actively tracks the stock market, watching this unfold was a textbook example of a catastrophic ESG (Environmental, Social, Governance) nightmare.

Shinsegae Group's Chairman, Chung Yong-jin, went into pure panic mode.

Fearing a massive nationwide boycott and a crash in Emart's stock, he fired the Starbucks Korea CEO (Son Jung-hyun) effectively immediately.

​Now, the situation has turned into a bizarre political battlefield.

Far-right trolls are visiting Starbucks stores en masse to "own the libs" and are generating AI images of the 1980 military dictator drinking out of the controversial Tank Tumbler.

​Corporate PR disasters don't get much worse than this.

Has there ever been a marketing blunder in your country that got a CEO fired on the very same day?
