Sheetz review: custom made salad

At the Sterling Virginia Sheetz I ordered custom salad to take with me on a car trip. Several hours later when I opened the salad bowl, there were French fries coated with cheese on top. Many of the fries were interspersed with the salad. I NEVER ordered French fries. I have a heart condition and cannot eat fried food.
My husband had unwanted fries on his custom salad, and he had none of the ham he ordered with the salad. And, if those fries were cooked in the same oil as shrimp, my husband was at risk for a severe allergic reaction; he is allergic to shellfish.
We have been Sheetz customers for years. I am appalled at this error and will not be returning to Sheetz.
