if those korean girls do become good quality girls, the pricing is still a big barrier which will end up with less customers and eventually those girls will move away from this shop. only need to wait a few weeks and should see them spmewhere else anyway.
a business should be competitive in both pricing and quality. it can't just jack up prices whenever it wants even if rent is high. give it a year and this thread will be empty bcos both shops will be closed.
