Yeah, I agree, sort of surprised at getting in. I had been texting at 8am for next day (because that's best way to get a morning or noon 1hr appt with popular girl at LSC) for a few weeks, and last time PO said appt available in afternoon two days later. So, I then I realized I could ask two days out despite not frequent.
I think the PO sort of likes me, I'm always respectful, never insistent. Also, I think she gets I'm old white long time monger, and maybe that's the reason.
I think there is a more traditional asian or Korean culture respect for old dudes, especially white Americans, some due to America's historical protectionist role against Japan, China, North Korea and nowdays the economic importance of America. Not that PO's or providers think about it like that but their politicians and culture get it, so it rubs off on younger Koreans. And Korea was never overrun at times with arrogant, obnoxious Americans unlike Europe, Canada, and Mexico.
