Triple Honk when powering down car...

Earlier today I ran through the drive-thru at Dunkin and then parked for a moment to get situated before taking off again. My fresh coffee was cold, so I shut down the car to go inside and get it replaced.

The instant I turned off the car, it startled me a bit with the dreaded "triple honk"...

There were no messages on the DIC or anything. I was able to lock and then unlock the doors with the button on the handle, and it started back up fine, without any messages about the remote or anything. Random anomaly, or was it trying to subtly tell me something? :confused:

Edit: I should note that all the doors were closed when I shut it off, as usual.

Are you opening and closing the door WITHOUT exiting?
Whether or not I exit the car is irrelevant. This is the description from the user manual:

Remote No longer in Vehicle

If the vehicle is on, with a door open, and then all doors are closed, the vehicle will check for RKE transmitter(s) inside. If an RKE transmitter is not detected, the DIC will display NO REMOTE DETECTED and the horn will chirp three times.
It will also triple honk if you leave the headlights on in manual mode...
The other day when I got to work I turned the car off, opened the door, pushed the lock button, got out, closed the door and immediately leaned over the windshield to remove some snow that the wipers had piled up at the edge and I got the triple honk.

Sure enough, when I got in the car to go home and turned it on, "Remote Left in Vehicle" was displayed. Apparently leaning over the windshield was sufficient to confuse the car about where the fob was (it was in my shirt pocket all day and definitely not left in the car). First time that has happened in 3.5 years (but I don't usually lean over the windshield when I get out).
