Sonic Drive-In

Went to this Sonic for lunch, went thru the drive thru and placed my order. 20 minutes later I am still waiting for my food as they are serving the cars in front of me and behind me. Finally got up to the window and the order still wasn't ready. I finally had to cancel the order. I will not return to this sonic ever again. Hopefully the other Sonic's in town are better than this one.
