Maybe she took a quick shower before she saw her next customer. But, yeah, not a fan of that. Might as well go to a fasthouse.
I saw a girl at Elite Spa about two weeks ago and I made her take a shower on her own after seeing a customer. I don't mind waiting for them to clean up and rest up for a bit. I'd rather not do that at all, but between showering and a few extra minutes to chill, it puts me at ease a little more.
