I would be mortified to be anything less than freshly showered for a guest, I also like time to tidy the room. I could never see back-to-back clients it would give me crazy anxiety!
I even bought my own shower hose, I find more and more hotels have the showerhead attached to the wall and I hate that because obviously I don’t want to get my hair and make up wet during my working day - most ladies don’t wash their hair everyday anyway - So with my hose I can just wash down my body, those shower heads attached to the wall are the worst invention ever!
