CAN someone please explain to me why people take a dog to a supermarket then leave it locked in the car?

On Saturday the temperature was 19c in my car so imagine what the temperature was in that car in full sunshine.

I reported it to customer service, waited half an hour and still no one came. If you care about your dog then please don’t leave it locked in your car in full sunshine. Don’t take them with you.
