I often walk around my neck of Bangkok.
I notice new shops, cafes, restaurants, beauty clinics, hair salons etc.
I say to myself, that one won't be here this time next year, and I'm usually right.
I understand people like the idea of having their own business, but seriously ... the location is poor, not enough market, too much competition, prices too high, too many locals & not enough tourists. But, many people still want to try.
