Never ever stolen anything from a shop. I was raised not to, and my parents owned a shop at a time and they knew shoplifters and it really upset them, especially when the business wasn't doing well financially at all, and some days we were struggling to get ANY money in, and then some stuff comes and tries to pinch something.
It might not be a lot, but that can mean that my parents would've spent an entire day (5am to 7pm) sat in a shop bored, away from their children, and then lost money that day.
As for other things, I've never stolen intentionally. On occasion I've ended up with someone's property by accident, usually as a result of borrowing and both myself forgetting to return it and them forgetting to ask for it back. But I know the opposite has happened for me too.
My parents have always been quite strict on stealing.
That said, they've knowingly pinched pieces of cutlery or glassware from pubs or restaurants before.
And with the family knowing. It's always been minor though, and usually taking something interesting.
My Dad has taken a fancy pint glass before, and my mum took a fancy dessert spoon and a cake fork.
They have pretty much only done this from pubs/restaurants that have provided terrible or rude service.
The pint glass though was a case of my dad getting a bit too drunk with family friends.
