Had to go to the courthouse to look some things up, I notified them that I needed to check a firearm, they opened a locker, I unbelted the holster and put it in the locker, and he gave me a laminated card with the box number.
No ID checks, no questions, nothing. Just a 'OK, follow me'.... 'alright, go ahead and put it in there.... when you get done, come back here and give me the card and I'll open it up for you'
I asked him how frequently people check weapons, and he said it happens about once a week, since noone usually brings a gun to a courthouse, but it's usually an employee, since they know about the lockers, and others don't.
A+ for Thurston county courthouse!
ETA: After checking my firearm, I accidentally left my carabiner (my key holder) clipped on my belt loop, and set the detector off ANYWAY,lol.
