I drove around the PYT RLD to see if there was any action to be had. I've been through there quite a few times in a cheap beater and have always been rejected outright, with a sole exception. This time I drove through in a nice car and although I was still rejected by most, they were polite and smiling when doing so. However, to my surprise, one nice looking girl said she would do it for 200,000 KRW. I wasn't much in the mood for action at that price, so I declined and moved on, but I was surprised that there was one that took me up on it. I don't know if it was the car that allowed me to have a better experience, but it was interesting to see a change of pace and I might rent a luxury car the next time to test the theory.
On a side note, there was an old ajumma in the 'be' row that waved me in. The girl working there was not unattractive and she was asking 100,000 KRW. I returned a few days later to find out that the girl working was Chinese. It was unusual to see a Chinese girl in a Korean RLD and afterward I asked the ajumma if she had any Korean girls. She said that there was one during the day and that she'd be back on Friday, so I'll head back then to see what my luck holds.
