Usually when having a mexican guest over they would prefer to have a home made meal and talk with the family more. When you bring in fast food meals they would see it as if you have no effort in becoming friends with them. Taking them to a movie wouldnt get to know the person better so they would like to sit and chat instead.
Answer: First off in order for the guest too be comfortable, the hospitality has too be good, for meals you can make traditional dishes or even ask the guest(wouldn’t hurt to try) if you were to go too a movie, fast food wouldn’t be ideal because it’s very basic and standard, you can always try to be open-minded and try something new or both parties can agree on where too eat.
