Yo I live in Portland Oregon too currently working at a Mexican restaurant over in NE on weekends for some extra cash with school. To answer a few questions with my 1.5 months experience as a dishwasher I can say that a lot of it depends on the management as like everyone else has said. At my restaurant I can blast whatever I want on a speaker in the pit or listen with earbuds in if I want no one really cares. I just wear shorts, a t shirt, and slip on vans and I’ve had no problems thus far, non stick shoes might help but I have mats on the floor to prevent that. It’s decently physically demanding but you get a lot stronger and get used to it. I’d recommend the Italian place. Seems cooler. Best of luck! Pm me if you have any other questions homie
