Review of Freddy's Frozen Custard & Steakburgers

Went to Freddy's in San Antonio because it was on my Find me gluten free app. I was very disappointed! The staff didn't really get the gluten free thing in fact I overheard the staff who were preparing the burgers saying why would she come here if she wanted gluten free. I talked with the manager who apologized, but I'm pretty sure I was cross contaminated. I will never eat here again Very disappointed
