As a former manager at a large Seattle-area gun shop, I can confirm this. A few years ago, the state added an “occupation” question to the state handgun form, but they don’t appear to care what people put when answering that question.
When they added that question to the form, there were no instructions given to dealers by the WA state Department of Licensing about what answers were appropriate or whether the customer had to be truthful, so our compliance specialist asked a DoL official during a state compliance meeting. The official said that there was no guideline for that question and there was no further collection of that information, so the DoL didn’t care what the person wrote for their occupation. The official actually said that they liked some of the funnier answers that people put down.
I’ve had customers write things like “aardvark wrangler”, “arm hair model”, and other ridiculous things. I put down “job” during my last handgun purchase before I moved to PA.
