One of things that impressed me about Canada were the newspaper boxes. People were trusted not to only take one paper from the box after they'd put their money in. I thought something like that wouldn't last 10 minutes in Britain before someone scooped all the papers out and threw them all over the street. But it turns out that in the late  1970s,in London at least, people were trusted to put their money into a cash box and take one copy of the Evening Standard from the rack at an unmanned newspaper stand.  I would have remained ignorant of this if I hadn't succumbed recently to borrowing the final series of the Sweeney on DVD from the local library. And there was the character played by Dennis Waterman using one of these unmanned stands. I was impressed.
