What is the best inexpensive dry dog food?

Bad manners include blowing one's nose at the table, picking up chopstick or spoon before the oldest person starts the meal, chewing with an open mouth, talking with food in one's mouth, sticking chopsticks or spoon straight up in a dish, stabbing foods with chopsticks, and picking up food with one's hands (with certain exceptions), using a spoon and chopsticks at the same time (usually, when you intend to use one of them, you have to put the other one on the table), making a sound when chewing foods or clicking a bowl with a spoon or chopsticks, stirring rice or soup with a spoon or chopsticks, stirring shared side dishes to select what you want to eat, removing a certain spices or ingredients from shared side dishes, being careless of coughing and sneezing to the persons on the same table (If you have a cough or have a fit of sneezing, you should turn your head to the side and put your hand on your mouth.), finishing eating too fast or too slow than the others on the same table (you need to keep pace with them), using toothpicks with the mouth open and leaving them on the table. In informal situations, these rules are often broken.
