Yesterday I went to M&S, despite only wanting 1 item I got a trolley to put DS (16 months) into so he didn't cause chaos and mayhem running around M&S. There were leaflets in the bottom of the trolley but I ignored those. We bought our item and left. Got to the car, unpacked and strapped in DS, put bag with one item in car, double checked trolley and found a packet of blueberries under the leaflets. Now we hadn't been in the food section so I know it hadn't been DS being light fingered it must have been left over from the previous persons shopping. To take them back would have meant getting DS out again and frankly I am much too lazy. So was I being unreasonable (and a thief) to take them home?
