Sounds like what my daughter did as a teenager - she had a handful of coins and dumped them in the coinstar. Out popped a receipt and her handful of coins. She looks at her receipt and come to find out she originally had 97 cents but now she only had 82 cents. Why? Because the coinstar kept their 15%, doesn't matter that they didn't do anything to earn it, LOL. She learned her lesson after that. Also soon after that our bank installed a similar machine and they did the service for free for account holders.
