I do. I clean up, and stack the dishes as best I can from biggest on bottom to smallest at top.Obviously trying to make the dishes easier to carry. I still tip the same. I just don’t mind helping someone clean up my mess. Even if I don’t have to help. I tip based on service… In a bar I frequent, I will even take the dishes to the bar, and throw away my trash. I don’t wipe the table, but I clean up major spills….
