Save A Lot complaint: The check out guy

I was out in the parking lot waiting on my friend when I heard a puppy crying out,, I thought at first it had got hit but when I got out of my car I saw it was in a truck with the windows rolled up , another car was setting there,, they said it had been setting there for awhile, I went into the store and went up the check out guy ( who is always rude to people) and ask him to make a announcement or something for the person who owed that truck,, he smarted off something and then said not his problem, luckily the person who owed the truck heard us and got the puppy out of the truck, I gave him a bottle of water for the dog, animal or person , no one needs to be left in the heat like that I was very upset about that but when your worker smarted off to me that was ridiculous and he has been very rude in the past, I hope you just get rid of him, you would get more business in that store if you did,, thank you
