Carhop Brought my food out, missing one of my drinks, brought out the wrong size drink and milkshake, then was missing marinara sauce for 8 piece mozzarella sticks. Then got told we charge after the first sauce. I’ve never encountered this at other locations. Not sure how they expect an 8 piece sticks to last with only 1 sauce.
Overall just disappointed in this locations.

Let's be honest sonic is just "okay", but this location has a track record for screwing up virtually every single delivery order. Buyer beware. Don't say I didn't warn you.

absolutely no reason to call corporate. They do not even return your call.
They will be rude. They will yell at you at this sonic. Do not bother even calling corporate they don’t even call you back
I really truly hope this sonic goes out of business.

If I could give this place negative stars I absolutely would! Employees and managers were beyond rude to me after taking 30 mins just to place an order. My drink is never right here and tonight I as no exception. When I nicely asked to have my drink made correctly the “manager” (what a joke!) snatched my cup from my hand then DUMPED MY DRINK OUT onto the ground! I’ve been a General Manager for a long time and none of my employees have EVER treated any customer like that. Will NEVER go back and I will be speaking to the GM AND DM.

We specifically asked for a drink carrier, didn't get one.
There's almost no flavor in our slush. This is a joke.
This used to be the better Sonic, in the area and I would drive the extra 10 minutes to come here but now, this is the fourth time in a row that they've been just the absolute worst.
NOT coming back to this location, till I hear EVERYONE HAS BEEN REPLACED.
This has gotten so bad over the last 8 months. The owner needs to pay more so they can get good workers. The ones they have now are horrible.
