I’m the youngest sibling with an age gap of 7-8 years to my older brother and sister. Growing up I was mostly alone, ignored, or often fought with them but eventually we grew a deep bond together through similar interests. The times I’ve spent with my siblings have been some of my most precious memories. I’m fortunate to have siblings that I could call my best friends and role models in life.
If the food costs less if I cleaned my own plates and cutlery, then maybe sure. I don’t think cleaning plates is degrading considering everyone does it at home anyway. Restaurants are providing service along with the food, and that includes the freedom to enjoy your meal without needing to clean up after.
