Tina has done the appoint switch-a-rooney with me a few times, not just with Coco. Changes the time when I'm almost there and sometimes even back again. Yes, it's because of walk in's. I complained after a few times so I got a 1 hr session for .4 that day ( it must have really bothered her to lose the extra .2 lol ) and it actually ran over an hour which wasn't bad because we hardly ever get the full time. And for anyone who doesn't know Coco, you only need a hhr with her. You will know why after seeing her.
