It depends. Might be against hospital policy, but it also depends on the circumstances and staff that catch you.
Get caught vaping nicotine after surgery while on oxygen and an RN catches you? Problem.
Get caught vaping THC, not on oxygen on oncology/hospice? Depends on the staff whether they'll notice it or not.
For the love of God can't we just make sex work legal, take the shame out of it, and STOP associating it with massage? PLEASE?!?
I've been a massage therapist for almost 20 years now and have got the point where the sex jokes hit with about the same impact as asking the cashier if something is free if the item doesn't scan at the register. I work in hospice, and not 3 weeks ago I had a patient's brother in law giggle and ask me if I gave his sister in law a happy ending. My inside voice said "no, sorry, she's still breathing so she has to keep dealing with you" while my outside voice pretended not to hear the comment.
