"Witnesses writing on social media said that customers at the cafe, who were watching an animated science fiction sitcom called 'Rick and Morty,' felt intimidated by the men, who refused to leave. The cafe referred to the attackers, some of whom wore sausages around their necks, as anti-vegan 'extremists.”
The NYT reports, noting that "[t]hroughout Europe, vegan cafes have become synonymous with the counterculture."
From the café's Facebook page: “They pulled out some grilled meat, sausages, fish and started eating them and throwing them at us, and finally they started to smoke... They were just trying to provoke our friends and disrespect us.”
