Sonic Drive-in - Del Valle

This has to be the worst Sonic I have ever been too. The restroom is filthy and smells like ****. The service sucks and the employees are slow at getting the orders out. It took 5 minutes for someone to come on and take my order at the menu board. The people taking the orders must be slow or something. I have to repeat myself 3 times because they can't hear. I would never visit this Sonic again. The managers are rude and don't care about the type of customer service they and their employees provide. I would rate this Sonic a negative star if there was one.
