Why was the French royal family rude? #movie

Raised as a royal marriage tool, Marie was strictly trained in noble etiquette. At sixteen, she was sent from Austria to France. At the border, she upset the maid by hugging her and had to give up her beloved dog. The French king welcomed her warmly, but her fiancé Louis was cold. At dinner, Marie was shocked by the royal family’s rude table manners and a woman’s bold intimate behavior with the king.
