Answer:
Wearing shoes or outdoor slippers inside the house. It is generally accepted in the Philippines to go inside a house with shoes that you’ve been wearing outside. Not in Korea. This is definitely considered unhygienic and rude. Nearly all houses have a designated area by the main door where you can leave your footwear and change to the provided indoor slippers
Korea has a very solid drinking culture with its own rules and norms. One of the strictest of these rules is “when you get invited to go drinking, especially by your bosses or seniors, you cannot refuse.” Turning down their invitation is akin to rejecting their company. (Not applicable in Philippines)
Unlike in the Philippines or in other places in the world where you could pay your bill at the table, one has to pay at the counter on the way out of the restaurant.
Unlike in the Philippines, Koreans do not have a tradition of inviting people over to their homes to have dinner or even just hang out, and it has nothing to do with the size of their houses.
If you ever get into a relationship with a Korean, please do not expect him/her to introduce you to his parents like what we do here in the country. Not even when you’ve been together for years. Most people introduce their partners to their parents just before they get married and the question right away is “when is the wedding?”
