Never leave anything visible in my car, like literally nothing in the car.
One time though I was parked by china town eating with the family, my fiance brought along a gift box she made for her bridesmaid invitation and left in on the back seat. Bum walks up and smashes my glass in broad daylight and takes the box.
Nothing valuable in the box but there were custom ordered cards in there that couldn't be replaced which pisses me off.
Checked my dash cam and there were people nearby when it happened that didn't even flinch when the glass shattered.
You can see him peeking through every window as he walks by in the video. Is also dragging a cart, likely to toss in all his findings
