yep, it's true:

looks like a deal was arranged in the coffeeshop between a buyer and a seller for nearly 10kg of softdrugs. police investigating this also found over 37kg of softdrugs in a nearby building belonging to one of the owners of Sarasani. so they've taken the license away for now.
too bad, I've never actually been to the oldest coffeeshop in NL.
