The absolute worst costumer service that can possibly exist!! My wife and I have been to the Mayfield Heights Sonic a total of approximately 7-8 times, scattered over a span exceeding a year since moving from New Mexico, and every time the service has been beyond substandard!
We were regular customers at the Albuquerque area Sonic restaurants and we never really had issues with service until moving to the Heights area. Every single time the service at the Mayfield Heights Sonic has been painfully slow, poorly prepared food and have messed/mixed up on the order without fail!! We have been thoroughly perplexed on how they can mess up even the simplest order. We tried to give them the benefit of the doubt with respect to maybe they employed new staff or management and thought surely they have to get better, but on the final trip have concluded that they are just God awful in every aspect and there is no hope!
The last time I was there to get a duplicate order prepared for free due to the fact they had messed up the order on the previous day and they promptly messed up that order as well!! On that final trip I noticed safety violations, employees stepping over things scattered about on the floor and just complete disorganization. I had directed the manager on duty to have the district manager contact me since the restaurant manager refused to provide me the number, but not surprisingly, I haven't heard back. To us this place ceases to exist. I would stay away if one values good customer service and sanity.
