How much does Buddhism affect most people's lifes in South East Asia?

For most people identifying as Buddhists in very Buddhist countries (Cambodia, Myanmar, Thailand), what are the most significant ways in which being a Buddhist affects their lifes? For instance, how common is - visiting the temple service at least once a month? - saying grace before eating? - intense meditation? My current image is that unless one's a monk, being a Buddhist is a formality for most people in South East Asia, mostly manifesting in Buddhism classes in schools, weddings and funerals.
