That's where schools such as Beaumont Etiquette come in. The consultancy agency offers youth and adult courses in British, Continental Europe and American etiquette. Founded by Myka Meier in London, the company says it puts a modern twist on traditional etiquette including dining, social graces, corporate protocol and more.

Beaumont Etiquette recently made its way to the U.S., opening up shop in New York City. Partnered with the famous Plaza Hotel, the school offers a five-hour etiquette intensive for a whopping $599. There are also course options starting at $75 for adults. Unfortunately, you'll have to be patient: classes are so popular they're sold out until May.
