The permit technicians at the counter are paid to be there to help you get your project submitted.
Many times we get frustrated with the process, but, there is really nothing the counter technicians can do to change the basic requirements. So if you get mad and frustrated easily please do not take it out on those trying to help you.
If you are unable to treat them as you would any other person that you work with, then hire a firm to go through the permitting process for you. It will be better for all concerned.
If you feel the person was short with you and not cooperative, then report it to the supervisor, remember to let their supervisors know when they have been extra helpful, too.
