John Law's Driver Training

the most terrible driver instructor I've ever met in my life. It's totally unacceptable for John Law to be 15 to 20 minutes late as a necessity of John, every time the time is scheduled for driver training. The training time is an hour and 30 minutes in length, but John Law has not provided and made it 1 hour and 30 mins just because he rushed to pick up his next student. More intolerably, he always does his something personal driving to somewhere else instead of focusing on the driver training.
