If the customer is disturbed by ingredients that are not even used, it may mean that you are using dirty dishes or kitchen tools. Then you should know that:
- water washes away everything;
- chopping boards, baking trays and pans - clean them with the option "enter context" or "exact manipulation" under the tap turned on above the sink;
- throw food and spices off the plates by lifting the plate, looking at the basket and pressing ONE time the left mouse button; then you can put them under water.
Why only once? If you press LMB second time, you will get rid of the plate...
