Old Men/Women dancing on the bus
Middle-aged to old men and women dancing on the narrow aisle of moving bus, loud Korean trot music playing inside the bus, it was very easy to see a bus like that in the 90s to probably early 2000s when you were driving down the highway. Those buses were, most of the time, for people who's on a travel agency package tour deal, while the bus's moving from one place to another, people dance on the bus as if they were in a nightclub, it was very funny to look at from the outside. We can't see that anymore in Korea, obviously because it's very dangerous for passengers to be standing while the bus is moving, maybe the police started cracking down on those buses and travel agencies, I don't know who did what exactly, but when they were getting stopped and fined for it, I guess that's when it started disappearing. You don't see a bus like that anymore. It was a very unique Korean culture.
To see that culture revived on this movie was very interesting indeed.
