Waited in drive thru @ Wendy's in Carthage Missouri for 30 minutes and when I got back to work took 3 to 4 bites of burger because I am a supervisor and was trying to eat quickly so I can take care of employees and looked down and by burger was raw in the middle. It was like they browned it on outside but didn't pay attention to the middle whether it was done or not. I have had several long periods of waiting in this Wendy's location for several months now but I love your burgers until now. My phone # is 417-310-**** if you want to discuss any further.
