In most dining settings and cultures, it is not necessary for you to pass your plate to the waiter when they approach to take away dirty dishes. The waiter is there to serve you and handle the table's clearing and cleaning duties.
When the waiter approaches the table to collect the empty or dirty dishes, it's polite to allow them to do their job without interference. Simply place your used dish or utensils at the edge of the table or within reach, making it easy for the waiter to pick them up. They are trained to efficiently and discreetly clear the table without causing any disruption to your dining experience.
If you're dining at a more casual or family-style restaurant where self-service or buffet-style dining is common, the practice may vary. In such cases, there might be designated areas where you can place your empty dishes for collection, or there may be signs or instructions indicating how to handle the dishes.
Overall, the key is to be considerate and allow the waitstaff to manage their tasks smoothly. If you're unsure about the proper etiquette at a particular establishment, observing others around you or asking the staff for guidance is always a good approach.
