Sharing my experience with a store lady
On my last day I decided to look for optical glasses in Namdaemun Market, I've read that it's a must-buy item when you're in Korea. I entered this one shop right after exiting the subway and the store lady kept following me while I was browsing for frame designs. She then asked "Just looking?", I nodded yes and she angrily let out a big "Aish". Immediately went out of the store and entered the shop beside them and bought my glasses. I was petty LOL.
Thankfully, this was my only encounter of this attitude throughout my 13-day trip. Sales ladies everywhere else were nice even on the subway station stores.
On a different note, I think one visit is enough and I won't be coming back. This might be because I've been to Japan multiple times and most things are far different - amusement parks, service, food, souvenirs.
Aside from Myeong-dong, there weren't much tourists/foreigners in the spots I've been to so it was quite a peaceful trip.
