Shopping in my local supermarket. I parked my car as normal, but noticed that the car next to me had the windows down. I'm not talking a little bit to let air in, I'm talking about every window being all the way down. My teenage DD said 'oops someone forgot to shut their window's'. I looked across and straight away clocked the baby seat. I said 'there's A baby on it's own'! We had a bit of a debate about it and we sat trying to work out what to do. We were probably sat there for 5 minutes, so plenty of time for the parent to have dropped off a trolley, or even go to the cash point at a push. The child was quiet still so I'm guessing it was asleep but it only looked about a year old.
In the end I took the licence plate and reported the car to customer services who immediately alerted security.
But WIBU to report this? I understand in a petrol station it is a different matter, but in a supermarket?
