I think this is the same one I saw a different article about quite a while back.

Speaking from my experience (getting a massage), I think the actual "massage" would be underwhelming, since snakes aren't there for the human, just doing
their thing. This is really all about the "novelty"... and hopefully no one panics & startles a snake into biting during their session. Not likely but could happen-
I wonder if they have insurance, or have patrons sign waivers?
