“Commemoration of Kristallnacht – treat yourself to more soft cheese and crispy chicken. Now at KFCheese!”
They issued a grovelling apology one hour later.
“We understand and respect the gravity and history of this day,” the message read.
“We are very sorry, and we will check our internal processes immediately.”
Human Rights Watch researcher Kartik Raj described the message as “truly and utterly vile” and Daniel Sugarman from the Board of Deputies of British Jews said it was “absolutely hideous”.
“Where to start with this? SO inappropriate, it beggars belief. Extraordinary,” Karen Pollock, chief executive of the Holocaust Education Trust, wrote on Twitter.
In a statement sent to Newsweek, KFC Germany blamed the alert on a bot.
They said the automated push notification was “linked to calendars that include national observances”.
KFC said it “sincerely” apologised for the “unplanned, insensitive and unacceptable message” and suspended app communications pending an investigation.
“We understand and respect the gravity and history of this day, and remain committed to equity, inclusion and belonging for all,” they said.
