Was asked to do something today that made me feel beneath everyone at my job

I work at a law firm. I am a legal assistant. I was asked to wash the dishes and clean up the kitchen table and floor. The table and floor had crumbs everywhere. The sink was full of dishes. Both were left nasty by my coworkers. I also had to clean out the fridges because the attorneys won’t throw away their food, and it ends up with mold. It honestly made me feel like crap more than I already do working here. No one else is ever asked to do any of this.
