First off i gotta say, Sonic is my all time favorite for slushes and shakes. And i always hit sonic, i travel around quite a bit and i just happened to stumble up to this sonic.
The manager was working the drive through, she was messing up an order before mine. I listened to the banter for about 5 minutes back and forth about how everything was wrong on the order. I then pulled up to the window and ordered a Banana Cream Pie Shake. She asked if i needed anything else and i said no. She then repeated my order back to me "So one Coconut Cream Pie Shake" i told her no. I wanted a banana cream pie shake. She then proceeded to argue with me that they didn't have a banana cream pie shake. They only had coconut. I told her i've been ordering banana cream pie shakes from sonic since i first went to sonic. She still insisted that this shake did not exist. I then told her never mind drove off and looked up the menu. Sure enough there is was...banana cream pie shake. Point is, watch your order carefully if you go to that sonic. But i never will again.
