"I recommended this restaurant to my mom because the review looked great compared to others at the airport. However, nobody attended to her when she was sitting there for 20 min, and she had to leave as the staff(s) seemed to be ignoring her. I couldn't believe her experience, especially since she was traveling in Germany alone for a few weeks, and had never encountered such an issue before. So, I'd like to know whether your restaurant was so understaffed on Monday at 8 PM that no one could attend to her with the menu for 20 minutes even with your best capability, or if your restaurant operates with a self-ordering system? Either way, her experience at your restaurant negatively impacted her last moments in Berlin, and I believe it's important for the restaurant to be aware of this."
