So what happens when you live in a society where opposite-sex intimacy is not acceptable in public? And what about if, in the same society, people live with their extended family?
You get Love Cafés!
Little cafés where you can sit in a booth that's hidden from view. Near work there was this cute love café down the hill from the main street. Little bamboo huts with bamboo blinds could be had with coffee or a smoothie. All of them come complete with a table and ONE long bench.
I tried once to get one. My Vietnamese teacher and I were trying to find a private place from the prying ears of Vietnamese youth (who had taken a liking to hearing me speak Vietnamese, going so far as sitting in the next table and silently observing me). The owner of the love café would have nothing of it, and refused to allow us in a booth. No same-sex couples (it's not like that... I pay him for lessons).
It doesn't matter because the Love Café has been destroyed by a storm. One day, while I was heading for a lesson, the main section where non-lovers would sit had complety collapsed. Nothing but a crushed straw roof.
