Phnom Penh and other cities in Cambodia are very crowded. When there is wedding, people don't go to the pagoda(church for Christian), so everything takes place at the groom house. And Cambodian wedding is complicated and it takes 2 days to finish.
This is only in Cambodia. People celebrate the wedding ceremony on the road. Sometimes, i have to drive through the wedding tent where people sit and enjoy their meal. Never see before, but I thought I was invited.
