Shouting is rude.
Marianne is eating at a restaurant with her husband Frank and her food was served undercooked.
Marianne wants to let the server know.
Marianne waits until the server comes close to their table and lets her know the food isn't cooked all the way.
Marianne yells across the restaurant to tell the server there is a problem with her food.
Marianne doesn't disturb other customers and is able to get her food taken care of.
Everyone is the restaurant stares at Marianne, and she now feels embarrassed.
