Upon arrival, an employee was cleaning the parking lot. The boy looked at us very much, which made us feel that we were being checked.

Then we went to order hot food and that was fine.

When that employee came in from the parking lot he was belittled by a colleague in the kitchen and another colleague stood up for him and then that girl who was belittling that boy started to belittle the other one too. We could hear everything loud and clear while we were on the other side of the restaurant. The discussions were extremely noisy.
