I think the answer is in this thread. People just don’t like the answer and want to blame the messenger. Part of it is Pubic Assistance, with his acerbic and irascible style, makes a good target but at the end of the day, there just aren’t many spas with a cohort of guys over 40. Of course there’s the exception here and there and the OP has listed them. And that’s great. Your best bet if you want an older masseur is to hire them off RM or masseurfinder.
It’s all good—older guys are great but despite us celebrating them the marketplace doesn’t support businesses employing them in significant numbers, for right or wrong.
End of story.
