We passed through Tuba City on the way back from the Grand Canyon. We stopped at the Sonic. It was terrible. Some youths in a vehicle were yelling profanities at each other, we went inside to eat as we were on a motorcycle and a staff person getting off duty was swearing with some friends.
It took 10 minutes or so before we were able to place an order (we were put on hold when we called in our order), and when we were finally able to order, an employee came out after 10 minutes and told us they were out of bacon (we ordered bacon cheeseburgers) and would we like fries instead. We had already ordered fries.
The floors in the dine-in and in the bathroom were sticky and dirty, as were the tables, inside and out.
When we finally got our food, the employee tried to charge us again (we paid when we ordered) and would not let us use the tray to carry our food. After 5 minutes, an employee came out and asked us if we had the correct order, and then tried to charge us again.
We regret having stopped at this Sonic (there is a McDonald's right there), and really regretted stopping in this town, since so many people were swearing and it seemed so dirty.
