As a provider,  besides being right on time ,do you prefer have a client be 15 minutes early or 15 minutes late..

Late as long as there is a courtesy text  
I'd rather have the gentleman run a few minutes late then pop up before I'm actually ready!  
Just my take, but then again, I am low volume or practically under the radar these days... I rarely see one a week with this full time job. Oye!
