Tonight marks the worst fast food restaurant experience I have ever encountered.  This is the last time I will ever visit a Sonic. No other fast food chain I have visited has given me a worse experience than the Sonic on Mckellips Dr. First of all, my son's order was screwed up twice. Then my husband went to pick up his drink, and the lid wasn't properly on the cup and it spilled all over him and his food. Lastly, not knowing that pretzel buns are only for hotdogs, I asked for one on my chicken sandwich and they used 2 hotdog buns and didn't even tell me they don't offer sandwich pretzel buns. Plus, they charged me 2 extra dollars for this creation. This isn't the first time I've had issues with this Sonic. Something is ALWAYS screwed up in the order or the location is out of ice cream. Not only that, any time I call to speak with the manager, they don't care. They barely offer an apology. This restaurant is pathetic and I have many choices in the area, so this will be my last visit to Sonic, or any Sonic for that matter.  It seems that Sonic has no intention of bettering their restaurants. What a shame. Beware and stay away!!
