Etiquette: When invited to someone's house in Mexico This is a very serious and real question. I will give more info in the "Additional Details" if allowed - I don't have room in the initial question. We have been invited to someone's house for dinner in Cancun. I assume (but am not certain) the lady is the one who has prepared this meal for us. This is a business relationship. What type of gift should we bring, and for whom? (Ex: wine for the man of the house? Flowers for the lady? Others?) I assume during dinner conversation, I should avoid business topics, but I'm not sure of customs here. Please advise. I think they are a little younger than my wife and me. How should we address the lady? (Ex: Sra. <husband's surname>? Another way?) Any other critical customs to observe? I know in Korea, there is a long list of protocols. I think there are some in Mexico, but I don't want to assume. Please advise.Background: A couple of years ago, I helped a company from Mexico with some of their technical challenges. when I brought them to Seattle for a lab, my wife (a Korean lady, and an exceptionally talented artist and cook) volunteered to cook for them and asked me to invite them to our home for dinner. I had never done this for any other customer I had worked with, but she wanted to because of their expressed interested in Korean culture. My wife REALLY outdid herself that night, and they had an exceptional evening.Now their company has taken off explosively, and their business is international. They have hired a CEO and other executives in specific areas to run their business. They have just opened an executive position in my area of expertise, reached out to me and asked me to fill it. As a result, they have brought my wife, son, and me to Cancun to interview for an executive position. One has invited me over to his house where his wife (I assume) will prepare a "Real Mexican Dinner" for us. I want to get the customs, and courtesies right for this.
