Yeah it would totally depend on girls and contacts or how quickly you make those contacts.. 10k per night is not an unrealistic number..
Hell my bar bill alone last night was 4800 and I am a cheap charlie expat and that was in a Nanai bar.. my mates bills were all around 2 - 4 as we were bell ringing like idiots all night.. Damn that Turkish Peper
!!! I guess that bar took 20 - 30k yesterday counting its daytime trade and as I said its not in any kind of location.
Soi Easy does not have any daytime trade though and is purely a nightime / girl bar atmosphere. It needs a stable and its location would require a stable of hotter than average girls.
