Burger King complaint: cross contamination perhaps?

I cant give you the store number or any names of the workers involved since I was not given a receipt or asked if I wanted one. I went to the poplarville ms burgerking at around 3pm today to order food for my family since I didnt feel like cooking. I ordered 2 whoppers no ketchup, 2 whoppers how they come, and 2 original chicken sandwiches. I understand that some fast food places require a lot of time to throw together 6 sandwiches, so I was expecting to be pulled up after paying. What I didnt expect was to see my order get passed to every person behind me and then passed back. 3 cars I saw this happen to and thought I know thats not my familys food being passed around like Coronavirus doesnt exist. Sure enough, it was. Same touched by everyone bag with the same napkin flying halfway out. sandwiches no longer fresh. This establishment is trash but now they are acting in a way that is actually going to KILL people.
