Sonic on Highland drive

As most who know me will tell you, I love a refreshing fountain diet coke. I have limited myself to one a day. So by the time I decide I want one I really want one. My husband and I went to Sonic on Highland Drive not far from our home. It was 3:45 pm. HAPPY HOUR (half priced drinks) I pulled up and pressed the button to order. We sat there. I noticed the button was lit so I assumed it was working. I said to my husband this is taking forever. I bet they want to hold out til 4:00 so we have to pay full price. He told me to push the button again. What could that hurt, right? Still waiting. After ten minutes without a response we drove across the street to good ol' McDonalds and gave them our business. Needless to say we won't be going back there.
