I asked Tony who could not think of anything special. He agrees about the flirting but that's kind of like saying don't get drunk , etc. "Mucho gusto" means nice to meet you and it's useful as a greeting. I think pronouncing a couple of phrases properly is a nice mark of respect.
If I am talking to a couple I am careful to address most of my attention to the wife. I'm old but single American women are suspect.
Good manners tend to be international. Where I live there tend to be handshakes where in Ca. there would be hugs.
Because the women are often more isolated they are likely to appreciate anything that includes them and does not make them feel out of place. Language is not as important as you might think. Kindness is.
