Hoax, suuure.
When the video first emerged, the narrative was that the woman was a transphobe, it's great that this spa is so inclusive, everyone tripping over themselves to defend the rights of males to expose themselves to kids, saying ''little girls should stop being rude and just not look'', etc etc...
...until they realised everyone was looking at them in horror like woah mate, what the actual FUCK?!
So then they had to change the narrative, which is now that this woman is a mighty fine actress who managed to get a bunch of other women in on her cunning stunt. I suppose she left that review 3 years ago too, huh? The one that details the same thing happening back then? Planted the seed and waited for the perfect day, three years later, to enact her dastardly plan?
Chinny reckon 
If it's a lie, why hasn't the spa denied this woman's claims? I know I would be if the name of my business was being dragged through the mud...
