What is a one-sentence summary of the following article?
Some Italian restaurants offer whole pizzas as an appetizer for the table to share. If that’s the case, you can grab a slice and hold or fold it to eat it. Try to stick to one slice until everyone in the table has gotten a piece. If you’re wearing nice clothes and worried about dropping some toppings on yourself, you can use a fork and a knife to eat your pizza, as long as there are appetizer plates for you to set the slice on. In any formal dinner setting where pizza is the main entree, rest the slice on your plate and use the fork and knife to cut it into smaller pieces. Avoid picking up the slice with your hands, which can be unnecessarily messy. This will keep you from getting sauce and toppings on your clothes or face while eating, and is easier for talking while eating. In a formal dinner setting, if you don’t know the proper etiquette for eating your food, you can always look to the host to see what’s acceptable. When the pizza gets to the table, let the host take their piece first, which will give you time to make note of what they do. Try to avoid staring at them while they eat, which can be considered rude. Instead, focus on getting your pizza onto your plate and then glance at them to see how they’re eating it. Depending on where you're from, the right way to eat pizza might be a controversial topic. If you're at dinner and someone is eating pizza differently than you would, avoid making comments about it. Follow the host's lead and eat the way they're eating to be polite. If someone makes a comment about the way that you eat pizza, take it in stride. Many people have strong opinions on the right way to eat a pizza because of where they're from. Just remember, all that matters is that you're enjoying the delicious slice in front of you!

Summary:
Eat an appetizer pizza by holding it if you’re at a restaurant. Show your manners by eating pizza with a fork and knife if you’re at a business meal. Follow the host’s lead if you’re unsure of how to eat your slice. Keep your pizza opinions personal to avoid conflict.
