Weird Rules For When You Meet Royalty

There's a particular way to perch in the presence of British royalty. People are expected to sit with an "egg’s width of distance" between their backs and chairs. They must also keep their chins parallel to the floor. 

Another rule forbids guests from crossing their legs at the knee. Feet can remain planted on the floor or crossed at the ankle.

Whatever you do, never turn your back on the Queen; it's incredibly impolite. She'll likely be meeting a long line of people, so it'll be hard to avoid facing the other way. Be careful just in case, though.

When you're at dinner with the Queen, do whatever she does. After sitting at the table, don't touch your food until she touches her food. This goes for the end of the meal as well. When she finishes up, you're done too. When she stands, you stand.

Don't bow excessively in the presence of royalty. In fact, if you don't feel like bowing, there's no need to do so. Quick, minor bows are appropriate, but they occasionally make royalty feel uncomfortable.

Don't get handsy when you meet the Queen or any other royal. If she reaches out for a handshake, you may accept, but don't go overboard.

Some Americans don't realize touching royalty is a major faux pas. Lebron James incurred the wrath of the British press in 2014 when he put his arm around the Duchess of Cambridge during a photo op. Etiquette expert William Hanson notes, "Americans are much more tactile than we Brits and this is another example of an American being too touchy feely with British royalty. You’d have thought they’d have learned by now."

If you're invited to dinner with the royals, arrive at your destination before the Queen. Additionally, expect to hang out until the Queen says it's time to go. Don't make any other plans on the same day; the royal engagement might run later than anticipated.
