Smoking with young children in the car?


So I work at a bank & I was in the drive thru today. I saw a mother & father drive up with a little one in the back seat in their car seat, couldn't have been older than 2 & before they pulled up to the speaker, both were smoking a cigarette with the windows rolled up. I personally don't agree with it considering the child is so young & secondhand smoke is horrible for a child's, let alone anyone's lungs. Just wondering if any of you have another insight on it?
