That's the problem Nicky Hurst of Country Fare Wholefoods and Fine Cheeses faced on Tuesday when she met Kate Middleton and Prince William in Wales, where they visited to mark St. David's Day. When the couple stopped by the cheese stand at Abergavenny Market, she went the casual route. "They are lovely," Hurst tells PEOPLE. "I wasn't sure what they'd be like and what to call them in terms of their titles. I called them 'Kate' and 'Will,' and they were really relaxed." On presentation to a member of the royal family, the correct formal address is "Your Royal Highness." Then "Sir" or "Ma'am" can be used accordingly.

"I asked William what his favorite was, and he said he liked a really rare Swiss cheese called Kaltbach. And I said, 'Here's some!' He was really surprised and said, 'I didn't expect you to have that!' " she recalled.
