I’m not in NC, but I would contact whatever agency licensed you as a M.T. I wouldn’t see any reason why having a second job should have bearing on your MT license.

Only if as a waitress
.
She becomes a taster of the products she serves to the customer
.
Not many people want to be near ***** with a person for a massage
that can not see the eye chart on the wall as it was meant to be seen
.
Because there is no telling what that person might grab hold of to give a work out with their fingers on
.
A little humor here of course
All in fun
You are not in jeopardy of loosing your license to be a masseur

Certainly. The only problem you might encounter in doing this is practicing message therapy while actually working as a cocktail waitress.
In other words, I would imagine a cocktail waitress would get a lot of opportunities to provide a few “deep muscle” massages while on the job… If you get my drift?
That would probably be illegal.

As long as you are not doing massage at the bar then you do not have a problem.
Being a waitress is not a problem, if you are working at a sexually oriented business, like a strip club, then you might have a problem.
