This was my experience, airborne near Hollister (CA) inbound to Salinas (CA) airport, SNS:
"Oakland Flight Watch, Aircoupe 1234, ten east of Hollister. Please give me current Salinas weather."
"Aircoupe 1234, Oakland Flight Watch. What's the identifier?"
"Salinas identifier is SNS."
"I know what the identifier for Salinas is. I need the identifier for your location near Hollister."
"I don't know the identifier for Hollister. Just please give me the weather at Salinas."
"The computer won't let me give you the Salinas weather unless I tell it where you are with an identifier."
"Disregard my request. I'll call on my cell phone. It doesn't care where I'm at!"
