A lot of people like to add to the amount after it's been tendered. Some are trying to be funny, many are trying to scam the high schooler into giving back extra money, not a lot really worry about what their change is.
When I recognize people who do this habitually they receive their change back in nickels and pennies.
I do it because getting back 3 quarters makes it easier for me to pay the toll booth later. I try not to accumulate pennies and nickels in my change cup. I also try to limit how many $1 bills I have in my wallet.
