Unbelievable! I have never posted a review like this. I just stopped in at this particular Sonic on Hwy121 in Melissa. We live nearby & we try to support our local businesses every chance we possibly can. It's a week before school starts, and our kids have been asking about getting a shake. I checked the Sonic website (for any current specials), and they have Half-Priced Shakes after 8pm. That sounds great, and my boys can hardly wait until the evening comes. Around 8:30pm, we drove to Sonic, went through all the wonderful choices, and pushed the button for service. When I began my order, I was abruptly cut off by the Sonic employee, and she said that special ended in the Summer. I replied by saying I saw the special online, and it said it did not end for another five days (Sunday). She shot back at me LOUDER this time, and again said "that special ended this Summer!" I mentioned that their menu screen right in front of me was ADVERTISING that VERY SAME SPECIAL!!! Again she refused, and said the special ended in the Summer. I started to ask if perhaps her location decided to end that corporate special earlier than advertised (even though they were still advertising it on their menu screen), but before I could finish my question, I was AGAIN abruptly interrupted, and she yelled to me, "OK, what do you want???"At this time, it became clear to me any business that chooses to treat their patrons/customers in this manner does not deserve my money - - or yours as well. I decided to take my money to another establishment. Then, as I drove slowly around the building, I passed the drive-thru area/window. There was a girl & a manager LAUGHING hysterically! She could hardly stand up she was laughing so hard. He yelled out, "Are you gonna let him treat you like that???", and he burst out laughing. I looked inside the Sonic, and the other five people were ALL pushing & shoving & laughing, making similar comments. Suddenly, one or two of them looked out the window, realized that I was watching them, stood up straight, and stopped laughing (briefly). As I drove away, I heard them BURST out laughing again.Needless to say, we will NOT be visiting that Sonic again. I simply wanted a nice ice cream treat for my three boys. They were very disappointed. One asked why "that lady" was so rude, and another asked why they would laugh about treating people in such a way. I have to agree.
