Don't wear overpowering (or ANY, really!) fragrance when you're getting a massage.
My first client of the day today was DRENCHED in perfume that smelled like the misbegotten child of baby powder and those blue things you put in your toilet tank. It made the back of my throat burn and my nose itch and run.
Plus, it had horrendous staying power: I could still smell it in my room at the end of my shift, four hours later.
Don't do it, people! Think of your therapists and take pity on their respiratory tracts! Thank you.
