    Over a 30 min wait in the drive thru and not more than 4 people have been here at the same time. This is absolutely ridiculous. Apparently the system shut down and now im late for work just bc yall can't keep ur ducks in a row. Fix the system and stop pulling cars up bc you can't keep your time down.

    While we were there we listened to two employees get into it about how orders are to be done. We would have left at that point but had already paid for our food. We started to pray over our food when the lady at the register decided to start cursing at her coworker. We picked our food up and went to the car to eat. We will not go back to this one in the future. Very bad management skills and poor customer skills.

    So I will start off by saying that the lady taking my order completely lacked customer service skills and was rude. What I wanted: 4 piece chicken tender combo, baked potato extra butter only, and a large strawberry lemonade with one more baked potato loaded with hot sauce for my coworker. So I start telling her my order. I say I want the 4 piece tender meal with sweet chili sauce. She asked me my drink and I said a large strawberry lemonade. She said they were out of lemonade. So I told her no drink just the tenders an a baked potato then. And before I could tell her what I wanted on my baked potato she asked if I wanted the combo? I said however you ring it up doesn’t matter to me, I just want it to be the chicken tenders and baked potato and no drink. Her immediate response was “come to the window.” It kind of rubbed me the wrong way because I didn’t even get to finish my order. But I thought maybe she was having trouble understanding me. So I pull up and the first thing she says is how much the total is. I told her that I didn’t even get to finish telling you my order. She immediately closes her window. Opens it back and asks what else I wanted. So I told her the chicken tenders and baked potato with extra butter. And she told me it comes with butter already. I proceed to explain how I would like extra. She said “like 2?” I said 4 would be great. And then I told her I wanted a loaded baked potato as well with hot sauce. She said “we don’t have loaded baked potatoes.” So I said the baked potato with cheese and bacon and butter sour cream. After that I don’t see her again. I guess she didn’t want to deal with me. A guy comes to the window and tells me they’re waiting on the 2nd baked potato with the cheese and chili. I said no, its cheese and bacon with butter and sour cream with hot sauce. He asks me to pull forward and I before I did, I said that I just wanted to make sure they heard about the hot sauce. He said he will make sure I get everything. So he brings out my food and I go back to work. Everything was correct besides there being zero hot sauce. 🤦‍♀️. I’ve never had a restaurant make me feel like such an inconenience before. Her customer service skills were horrible. His customer service skills were much better, but it sucks that I can especially ask for something a few times and it still not be in my order like I asked. This was in between the 1:05/1:20 pm times on 2/8/2026. Was my order that complicated?

    I ordered a junior bacon cheeseburger with pickle, lettuce, tomato, onions, mayo, and mustard and medium fries at the pickup window for my wife that was at home. We actually live 3-4 minutes from this location off of John Sevier highway. To begin with it was cold, they totally left out the lettuce and tomato. It must have been under the warmer for who knows how long, It was totally disgusting. The problem with picking up food like this is the inconvenience of having to drive back to file the complaint about it and take it back. If you're going to pay over $6 for a hamburger and fries, it needs to at least be fairly hot and include the items the way its ordered.This is why I stay away from Wendy's and places like this but, my wife insisted she wanted one so she has been to this location in the past with no complaints until now. This was totally unacceptable and I totally blame management. Shame on Wendy's!

    Told to pull up after paying and sat over 15 minutes waiting for 2 breakfast sandwich combos and an oatmeal bar. When food finally came one of the sandwiches was literally cold to the touch and there was a random sandwich we didn't order in the bag. Food was not very good at all
