Choose absolutely any other Sonic in town but this one and trust me, you'll have a happier day.
I complained that their drinks machine had malfunctioned and was dispensing only carbonation and no syrup and they tried to tell me that straight carbonation without syrup was called "Sprite." I know what Sprite tastes like and I know what it tastes like when a drinks machine runs out of the syrups to turn carbonated water into various soft drinks. Wanted me to pay extra to fix THEIR mistake.
It wasn't the first problem I've had with this location, but it will be the last.
