It's definitely not a matter of unreasonable, I've been there twice myself, first time was very bland though not overly bad, second time was godawful. They never seem to have more than 2 girls in house - your review is the first I've heard otherwise - and overall it seems like they don't care about their customers, just getting that cash flowing, hence the low prices and unnerving staff (young social media lady kept pushing for my number, and older mamasan rushed the booking process both visits, despite me being the only customer at the time(s).)
I want to give Forever 19 another chance, but they're gonna have to massively step up their game.
