If the cashier gave you more change then what the til says. Would you say anything?

Its happened a few times to me with these new owners at my local supermarket. I was in the there today. My grocery came to $14.35 I had $15. He tried to give $5.50 change. So I had to point that out. Even had to tell him how much change to give. His boss was at the next register. He wasn't too happy.
