Panera Bread complaint: Panera staff

I am a panera customer and also a Doordash delivery driver. Everytime I go to pick up a delivery order I feel so much animosity directed my way from both management and associates in this panera restaurant because I happen to be the go between for Doordash and Panera. This morning I went in to get a customer pick up and the employees told me that I had to make up the customers coffee. I have never been told to do so by any establishment before that I pick up from to do so. I do not drink coffee, nor do I know the procedure panera uses to make a pick up coffee for someone else. Doordash has since told me I am not to do that, and that they need to do it themselves. I feel so uncomfortable going into this establishment now even as a customer separate from my delivery job because of the attitudes and animosity from staff of all positions.
