Yeah, very hard to justify the value proposition. Especially for me because I don't really care for BBBJ. It's probably the lowest rank in the things I prioritize when having sex, way below FS, DATY, and DFK.
Plus, I reckon it would be a lot more confronting and risky for the girls to have to do BBBJ instead of CFS. If BBBJ was the optional add-on, it would make more sense.
Of course, it would then mean that they would have to seriously rejig their entire fee structure to remain competitive.
Biggest problem is the 30 min booking, priced at $165 after 1st Nov increase. The going rate for 30 min massage + HE is about $95. That puts the value of the BBBJ at $70. If we replace that with $100 for the FS, it comes to $195 for a 30 min booking. Add $70 for BBBJ, $265 for 30 mins, same total as before. That price gonna make them uncompetitive against the likes of Ginza, even without the extra for BBBJ.
It could work for longer bookings though. 45 mins would go from $190 to $220 ($290 for the lot), 1 hour from $220 to $250 ($320 for the lot). That's still competitive I reckon.
