Panera Bread complaint: Humiliated by being accused of stealing when I was picking up orders for my colleagues

My colleagues and I all placed our orders online for pick up. I drove down to the restaurant and placed another take out order for a colleague who did not use the online app. While I waited for that order to be made I checked the shelves to make sure that the three other orders, that had been placed for myself and my colleagues had been prepared. They had been so I returned to wait on the last minute order. Once that was ready I collected the other orders from the shelf. As I walking towards to door a staff member yelled at me to “stop” and demanded to know why I had taken these orders. I explained the situation, his response was “well people steal”. This may be true but I have never stolen in my life and to be accused of it infront of a large group of people is highly humiliating. Why would I think about taking orders from a shelf where staff can clearly see me?
