Starbucks marketing stunt backfires as South Koreans destroy tumblers and boycott chain after it launches promotion on anniversary of historical massacre

Published: 16:19, 6 June 2026 | Updated: 16:23, 6 June 2026 Starbucks was forced into a humiliating climbdown after a marketing campaign launched on the anniversary of one of South Korea's darkest chapters sparked nationwide backlash.  The coffee giant faced calls for a boycott after promoting a new range of 'Tank' coffee tumblers on May 18, which was the same date as the anniversary of the 1980 Gwangju Uprising, when pro-democracy protesters were violently crushed by the military. Furious customers smashed Starbucks mugs and tumblers, deleted loyalty apps and demanded refunds on prepaid balances. Meanwhile government agencies suspended ties with the chain, the billionaire chairman issued a televised apology and the CEO was sacked.  The controversy erupted mere hours after Starbucks Korea launched its 'Tank Day' promotion, which was intended to advertise the new tumbler range with 'spacious volume' for larger coffees.  Instead, critics accused the company of insensitivity for using the word 'tank' and declaring May 18 as 'Tank Day' on a date that such a historical massacre took place. Known as 5/18, May 18 marks the start of the 1980 Gwangju Uprising, when paratroopers were deployed to suppress pro-democracy demonstrations against ruler Chun Doo-hwan.  Victims' groups say hundreds of people were killed during the crackdown that spanned over 10 days.  Furious customers smashed Starbucks mugs and tumblers, deleted loyalty apps and demanded refunds on prepaid balances The controversy erupted mere hours after Starbucks Korea launched its 'Tank Day' promotion, which was intended to advertise the new tumbler range Critics accused the company of insensitivity for using the word 'tank' and declaring May 18 as 'Tank Day' on a date that such a historical massacre took place The campaign also drew criticism over its use of the phrase 'thwack on the desk', wording that echoed an explanation given by authorities after the 1987 torture death of student activist Park Jong-chul.  Authorities initially claimed Park died after an officer used his fist to 'hit the desk with a thwack'.  The slogan was reportedly chosen with the use of an AI tool, however it was discovered the material was approved by some managers who hadn't even opened the email attachments containing it.  Starbucks pulled the promotion within hours of its launch, while chief executive Son Jeong-hyun was dismissed the same day as public anger intensified.  His dismissal came after he issued a statement, where he apologised and pledged company-wide education on historical awareness and ethics.   The fallout blazed through social media, with protests held outside Starbucks stores and videos circulating online showing customers defiantly destroying branded merchandise.  Billionaire Shinsegae Group chairman Chung Yong-jin, whose company operates Starbucks Korea under licence from Starbucks Corporation, issued a written apology on May 19 - but to no avail.  Card spending at Starbucks stores fell sharply in the days following the controversy while customers sought refunds from hundreds of billions of South Korean won, the nation's currency, held on prepaid Starbucks cards.  As tensions remained high, Chung issued another apology on May 26 at a televised press conference, during which he bowed three times. Bowing is an integral part of South Korean culture and is used to convey respect, apology and gratitude.  He said: 'I take it very seriously the fact that many people felt deep pain and anger because of Starbucks Korea's inappropriate marketing campaign.' Chung's second apology was met with further backlash, as the elder brother of student activist Park Jong-chul wrote to police calling for Chung and the former CEO to be charged for insulting the memory of victims.  As tensions remained high, Chung issued another apology on May 26 at a televised press conference, during which he bowed three times. Bowing is an integral part of South Korean culture and is used to convey respect, apology and gratitude Chung and Son have since been classified as criminal suspects by police.   The row also reached the highest levels of government, with ministries suspending partnerships with the chain and South Korean president Lee Jae Myung condemning those responsible for the campaign as 'low-class peddlers'.  The Democratic party's leader Jung Chung-rae called for Chung to kneel before the nation in reparation.  Starbucks is particularly popular in South Korea, ranking as its third-largest market globally, with more than 1,200 stores.  An investigation led by Shinsegae found no evidence the Starbucks campaign was intentional, while Starbucks Korea urged customers not to direct their anger at frontline shop employees.  Starbucks Corporation, which licenses the brand but holds no equity in the Korean arm, said it was 'deeply sorry for an unacceptable marketing incident'.  The company, which holds its headquarters in Seattle, said: 'While unintentional, this should never have happened. We recognize the deep pain and offence this has caused, particularly to those who honour the victims, their families, and all who contributed to Korea's democratisation. 'We sincerely apologize to the people of Gwangju, to those impacted by this tragedy, and to our customers and communities.' The company added it was conducting a review on internal standards and training to make sure the incident was not repeated.   No comments have so far been submitted.
