I am not advocating shoplifting, but we all did something dumb as a kid. What is your story?
Me, I was 2 years old and at Tim Hortons with my mother and a family friend. This was almost 50 years ago and Tim Hortons still had servers back then, so there was a cutout in the counter for them to go in and out. The donuts are in racks behind the counter. I had had a chocolate donut paid for by my mother, and apparently I decided I wanted another, and I was so little I nipped behind the counter when nobody was there, helped myself to another, and was only discovered when my mother noticed me polishing off a different donut. She did pay for it and everyone laughed, I was just little and it was funny. Sadly the quality of Tim Hortons donuts has gone way downhill over the intervening years, as older Canadians know.
Kids just do dumb shit sometimes. Nothing to feel bad about. You did the right thing.
