hair dresser

My hair dresser annoys me at times. She over books people to get their hair done at a certain time and doesn't get to them for at least one hour and a half. If she knows that she is not going to get to a person within 15 minute of booking them for the appointment then she should not over book people. What does she think that I am just going to keep sitting there especially now that the weather is starting to get warmer. I don"t have time to sit there to hear all the gossip of the day. I have better things to do with my time then this continues I will have to start looking for someone!
