If you've been to the rural USA you'd know it's just high-trust (and the middle of nowhere). They're pretty common for low-value things like corn and farm produce; but I've seen syrup and honey, too.

There might be a camera, but what would you do with the result besides some vigilante frontier justice? No cop anywhere but daytime children's TV is going to investigate the Case of the Stolen Syrup.

We once went to Florida and saw some open orange farms. We wanted to buy some, but there was nobody in sight - we got very confused until we saw a box which said "$X a bag"; there was a sack of bags nearby. My mind was blown.

That's a matter of scale. https://en.m.wikipedia.org/wiki/Great_Canadian_Maple_Syrup_H...

Or Japan apparently, according to some of the comments in this thread.
