I trolley shamed 3 people while with the dog at Tesco earlier. On this particular walk, we often do a half way by a Tesco, and waiting, some woman leaves her trolley inches away for another car, and just gets in. I walk over and said hard work isn't it, walking 15 steps, and took it back myself. The classy one gave me the finger. Next some bloke does the same. I said mate, no wonder the NHS is in crisis, how hard is it to put that back and think of other people's property. He looked at me, and drove off. Another woman does it next. I take the trolley as shes getting in her car and said watch this, and walked the EIGHT steps, counting them out as I go, returning her trolley. Shamed, as I'm saying what happened to other people, she drives out an opposite way, not to pass. Again mind you, all of them also decided to park as near to the tesco opening as possible.
