Mexicans like it when you say everyday words like good day, thank you, please, etc. in Spanish. Mexicans value respect for their traditions and culture. Political and religious matters are taboo. Corruption and generally a critical attitude towards Mexico should not be addressed. Mexicans are a very proud, patriotic people.
Mexicans have their own interpretation of punctuality, so they sometimes turn a blind eye. The “mañana mentality” is typically Mexican. Why rush when something can just as easily be done “mañana,” tomorrow? Patience is required at the authorities, where you are immediately given to understand that you should be happy to get an appointment at all. It had taken us only 5 hours to cross the border from the USA to Mexico alone. Waiting times of several hours are possible. It is important to remain calm and polite, otherwise nothing will work at all in case of criticism.
