Final answer:
The Mexican workers' attitude to time, which resulted in wedding arrangements being late, is an example of a 'polychronic time' orientation that values flexibility over strict adherence to schedules.
Step-by-step explanation:
The attitude regarding time that Tom and his fiancée Susan experienced in Acapulco, Mexico, where workers and arrangements for their wedding arrived late and the local workers advised them to be flexible, is considered polychronic time. Polychronic time refers to a cultural time orientation in which people are comfortable handling multiple tasks or issues at the same time and are less focused on a strict adherence to schedules and punctuality. This contrasts with monochronic time, which emphasizes schedules, punctuality, and the sequential completion of tasks, and is commonly seen in Euro-American cultures.
