In drive thru right now trying to pick up some food for a family member and the person expediting the window has a really poor attitude and has been rude throughout the entire transaction. So much so that a young man ended up taking over the transaction. Im not really sure what we did to be accosted. The girl had trouble hearing us so we had to speak at a greater volume to hear us and it seemed as if she had us repeat ourselves intentionally just to continue being rude. I don't want any refunds or free gifts etc but maybe train the people on the window to have better manners? I could understand how she may have thought we were being aggressive when giving our order but we were simply trying to be heard since the girl had such trouble hearing us in the first place. We also asked that our fo

stopped in on way home tonight. I placed an order on the app in the stall (I do this to use my rewards) at 8:10pm for 2 Coney dogs, chili cheese tots, and 2 drinks. After about 15 minutes I noticed that my order status on the menu sign was gone and still no food. There were cars that pulled up after me and in drive thru that had already received their orders and left. I waited another 5 minutes then pressed the red button again and asked about my order. The guy that answered asked me the order name and the replied, "oh it's sitting over here, we will get it out to you". They did bring it out after that, and the young lady was nice. I reached into the bag ad checked the temp of the food and the dogs were cold, the chili on the tots was still warm. it took me about 8 minutes to get home, at

It's a hit or miss at this sonic. Some days they are quick and some days they are slow. Depending on who's making your burger depends on if everything slides out on the first bite or not. Too much sauce is always a problem.

Seems like they can NEVER get the food right. Tonight ordered a garlic butter burger with NO onions. What I got was an onion burger with NO garlic butter sauce. When I order shakes and request extra choc or Oreos I’m charged for those but either get NONE or very little. This is frustrating. The amount of money spent on 1 meal going out and they can’t get stuff right.

I eat at sonic alot, and in fact I eat here 3-4 times a month on average. Generally the food I'd fast and good, that's why my meal yesterday surprised me. I ordered the Jr burrito, which I have had dozens of times. It's just like the regular ones just not as much different things in them. I ordered sausage and egg. When it came out I was surprised by the weight of the bag, it didn't feel heavy enough. I left to head to my next stop and when I pulled it out I found this Itty bitty burrito, it was like 2" long! And pretty much nothing but tortilla, very little egg and sausage. I was too far away to go back but seriously, this shouldn't happen, someone wrapped this up and thought it was OK to serve to a customer
