Frustrating

I like the convenience of the gym I recently joined, it's so close to my house. The training is leaving a lot to be desired. Or should I say, the lack of training... Last night, after waiting for him for almost 15 minutes (I was on the treadmill and elliptical warming up) my trainer had to reschedule my session. Two of his trainers were out and since he's the trainer manager he has to cover their appointments. The sessions are only 30 minutes, so he would have had to stop before my session was over. We rescheduled the session for today's lunch hour. I show up and he isn't even there. The guy at the front desk, I think he's the owner, gets through to him on the phone. He says he'll be there in just a few minutes. By 26 past the hour I give up and leave. That's twice now he hasn't been there for a scheduled session. I don't care if they say it's on the house. I NEED A TRAINER.
