1, the normal way to eat pizza is to eat pizza with a knife and fork, with a left fork and a right knife. Don't raise your arms when cutting, keep close to your body.
If you eat pizza with your good friends, you don't have to care so much. You can choose to grab it with disposable gloves.
Besides, you can't eat pizza with black pepper or garlic sauce. If you must, you can add a small amount of olive oil. Take a big drink instead of a small one, which will help you swallow the dough. Drinking a drink like carbonated drinks will help you get rid of the greasy feeling.
