HARASSMENT AT A BISTRO

Arrived in Brussels 24h ago. Went to a bistro to get something to eat. Two guys at the bar stare at me. “Russian” they say. I continue to stare ahead, no eye contact. “Hey, you are Russian. Da. Da” I throw an angry look. “Do you want a beer, Russian girl?” Silence from my side. I feel mad and helpless. Who the hell needs to say such things? Of course, no one interferes.
