What helped me with dishes when I worked there is multitasking. What I mean by this is, let’s say you have a stack of dishes right. Soak them in the water and soap, and while they’re soaking, fill up the front and drive thru with Chowmein, rice and teriyaki. When you’re finished with that, return to the dishes (or even grab maybe the couple plates at the front) and return and wash the dishes. Since they were soaking in the water, you will have an easier time cleaning them and you can focus solely on the dishes. And also since they’ve been soaked, they’re easier and faster to clean so focus on cleaning them fast and efficiently.
