The manager ( Hong? ) should have done a better job in this case. A regular customer who she knows likes extra services and she offers him a masseur who does not provide them without informing him of this beforehand. If she had said " young, pretty, good massage, no HE " then you have the info to decide. Considering how many UKP reviews the place has Hong should have made Jasmine aware of this element of the business.
I have no idea what proportion of customers to the shop are solely after a non sexual ( legit/innocent ) massage as Jasmine sounds perfect for those.
Another lady coming in at the end just for the HE would be worse than nothing for me.
