I still do the majority of my appts in person and when a client is more than 10 mins late, it puts pressure on me as I also go back-to-back. 

I cant stand when a client is a no show.......you know what??? Call me and tell me youre too hungover (ill respect that) or tell me your were abducted by aliens. Just dont leave me hanging.

My 11am was a no show. Grrrrrr
