The Guardian: Starbucks Korea to temporarily shut all stores for history lesson after bungled coffee promotion
"...The Gwangju massacre is a painful memory for many. Over 10 violent days, paratroopers crushed pro-democracy protests against military strongman Chun Doo-hwan. Victims’ groups say hundreds were killed.

It also featured the slogan “thwack on the desk”, evoking a notorious police explanation for the 1987 torture death of student activist Park Jong-chul. Authorities falsely claimed he had died after an officer “hit the desk with a thwack” during questioning.
Marketers chose the “thwack” slogan after consulting an AI tool for suggestions, Shinsegae Group said...."
