Dollar General review: alan throwin money back at customer

I went in dollar general to get drinks and arrived at the cash register to pay for my drinks and the cashier (allan) threw my change back at me. this event happened on 6/2/13 at 1;25p.m. This is not the first time something like this has happened. He treats me unfairly as a customer. He is really rude and disrespectful to me. He always has an attitude.
