I took a class on protocol and etiquette yesterday, which was also very interesting. Although I’m guessing it’s unlikely that construction engineers get invited to many formal dinner parties or receptions, you just never know. Plus, they had a lot of other useful advice, including business cards, the proper use of silverware with both American and Continental styles, and how to handle a dinner party when a guest appears with more wives than expected. I couldn't quite convince the presenter to say the American style is better than the Continental style, but I tried.
