Sonic (Cockrell Hill)

Terrible service. The employees who work here are unfriendly and unprofessional. The restaurant was clearly open when I pulled into the drive-in. There were several cars that had ordered food. As I was placing my order the employees turned off the lights and said the place was closed for the evening. I drove off but noticed that the drive-thru was still open. What terrible employees. How hard is it to take one more order or have the decency to direct me to the drive-thru? This place has lost my business.
