Stopped in to get a stamp for my aviation passport on a Saturday. Chart supplement indicates they open at 0900. Waited around until 0920 with no one in view and facility locked. Called airport manager and the call was forwarded to voicemail after 2 rings.

Poor customer service. Not friendly or welcoming. Everything I asked for seemed to be taken as an inconvenience. Recommend KBCB instead just across the river.
