I was in this store on the 2nd of February. After I had given the middle aged woman with an accent behind the counter a $20. bill and then decided to add a piece of candy , the woman told me I HAD NOT GIVEN HER ANY MONEY! She was perfectly stern and comfortable with this scam. I'm sure she's done it many times.
I was adamant. I knew I only had two $20. in my wallet. She was quite fierce but eventuallly she gave me the correct change. She must take advantage like this all the time.
