Owner's sister with a bad attitude

My boyfriend and I had just finished a meal & waiting for the bill when I leaned my head against the wall because I felt tired and my boyfriend leaned over and kissed my cheek, this owner lady starred at us and then shook her head, when I asked if she was joking, she walked to our table & started moaning at us that this is not how we should be acting in a family restaurant! This obviously left us utterly speechless & embarrassed! I then started making a scene about how she can treat her customers like children and make us feel this way & that's when she lowered her voice and said \you are making a scene
