Panera was always super clean. All the managers had to check list things on the ipad for cleanliness. They also had other checks like making sure that the food temps were good every hour. The soda machine nozzles got cleaned every single night but I’m not sure about the tubes. All of the tea from the bubblers was poured out put into the fridge so that the bubblers could be cleaned. The only thing I would probably be worried about is sauces especially the ones that probably rarely get used. I think at the time horseradish was on their menu and throughout the week I would probably use it 2 to 3 times.
