4 mistakes to stop making at high-end restaurants, according to an etiquette expert

• Business Insider asked an etiquette expert what people should avoid doing at high-end restaurants.
• She said diners should never disregard the wait staff or arrive late to their reservation.
• She also recommended checking the restaurant's dress code to avoid dressing inappropriately.

Going out to a high-end restaurant can be a luxurious experience. But for patrons who are used to more casual-dining experiences , eating at a fancy restaurant can be stressful.

To learn more about everything from how to dress to how to address the waitstaff, Business Insider asked Elaine Swann , a lifestyle and etiquette expert, to identify four common mistakes diners should avoid making at high-end restaurants. Here's what she said.

Don't disregard the wait staff.

When dining at a high-end restaurant, patrons should expect to receive a higher level of service. For this reason, Swann said it's important to build rapport with the wait staff.

In the past, "I've heard people say, 'don't interact with waitstaff,' and that's incorrect, and I think that's quite snobbish," explained Swann.

"Instead, you should communicate effectively with the staff, find out their name," she told BI.

She also suggested calling the server by name when making specific requests or asking questions about the menu. According to Swann, this can help set the tone for an enjoyable dining experience.

Be sure to dress appropriately.

According to Swann, another common mistake diners make is dressing inappropriately.

"You might live in an area where the attire is more casual and shorts are acceptable, but that may not be acceptable in some higher-end restaurants," she said.

To avoid this faux pas, she recommends finding out the dress code in advance to ensure you're appropriately dressed.

To do that, "You can check the website or call ahead," she said. "And then another thing that I encourage people to do is look up photos."

For example, Swann recommends looking up the restaurant's social media pages to get an idea of what appropriate attire may look like. She also suggested looking at the restaurant's hashtags to see what other people who have dined there wore.

Show up to the reservation on time.

Swann said another mistake guests tend to make at high-end restaurants is showing up "fashionably late." In fact, she said showing up on time helps to ensure the service goes as planned.

"The service at the high-end restaurant is based upon everyone being there at the same time, on time," she said.

According to Swann, being late can impede the flow of the service.

"It's important to respect people's time. When someone gives you a time to show up, they're expecting to start within the flow they have designed. And It's quite disrespectful to show up late," she said.

Don't forget to tip.

"You should always leave a tip at every restaurant you dine at, regardless of if it's high-end or your standard mom-and-pop restaurant," Swann said.

However, she noted that although 20% of the bill is the standard tip at a regular restaurant, the tip at a high-end restaurant should be a minimum of 20%.
