Jittery Joe's of Macon Georgia

Unfortunately, Joshua Cup went out of business and so I'm here at Jittery Joe's to catch up with work and have a cup of coffee with a cheese Danish.  I placed my order and the total came up to $4.00 gave the associate a $10 bill.  And she quickly gave me my danish and a small coffee.  But I was waiting for my change and she never did gave me any money back.  So I'm going to let it go and not say anything to see if there's a pattern.  Is not like they were super busy, because there was only me and another person in line.  Anyway, let me know if any else experience the same.
