It's difficult seeing a CA in training
Was at the ignition interlock shop yesterday, getting my unit calibrated.
There was a 22 year old there. She was getting her interlock installed. They have you watch the training video in the waiting room, and there is a display device in there that you practice on. She kept failing the practice test when blowing. At least the installer was polite about it when she said it must have been the food she ate.
