I ordered my food and shakes (for 2) and waited 30 minutes or longer and finally decided to leave. If someone would have communicated what the hold up was I would have been fine with that, but just leaving me hanging is not acceptable. The time before this I waited for 15 minutes and no one even came on speaker to take my order (yes i pushed button). What is wrong w/this place? I'm hoping not all Sonic locations are as bad as the one on north valley mills drive, i will not be back.

I was told at the stall that they were only accepting cash payments, which immediately raised concern.
What makes this unacceptable is that I was able to place and pay for my order through the Sonic app with no issues at all, using a digital payment. That confirms the store was in fact able to accept non-cash payments, making the “cash only” statement false or, at best, misleading.
Whether this was done to reduce order volume, avoid app orders, or push cash tips, it reflects poorly on staff integrity and customer service. Guests should not be turned away or given incorrect information because employees don’t want to work.
I hope corporate reviews this location’s practices and retrains staff on proper communication and policy adherence. This experience seriously damaged my trust in this store.

I love sonic and would have loved to have gotten some food had I been able to order. I pulled in to an empty parking lot a good hour and a half prior to closing which should have been my first clue sat in multiple different stalls for 15+ minutes waiting for someone to answer the call buttons all the while this girl knew I was there. I see someone else come and go without food because I assume they didn’t answer them either. I give up and go through the drive through which I was going to do anyway because I had 2 separate orders one of which I was going to do in the stalls, the other in the drive through. I pull around and after waiting a minute the girl answers. I say “hi there I have 2 separate orders” before I can even get my sentence out the girl cuts me off with an attitude saying “We only take 1 order in the drive through at a time” to which I finally lose it and say “Ya know what nevermind thank you have a good night” and drove away. It shouldn’t be this difficult to order food. I wish I could give 0 stars. And I wish I could say this is the first time this location has given me trouble.
