Can I get the correct amount of change the next day?

So we went to AutoZone today and we bought 2 items that came up to $30.44. We paid $100 in cash. Our change was suppose to be $69.56 but because we were in a rush, we didn't check our change and receipt. The cashier had given us only $9.56. I noticed it too late. If we return to the store tomorrow morning do you think we will be our money back?
