Line was ridiculously long so I decided to use the "avoid the line" kiosk. After ordering & ready to submit the final order, I was prompted with an error message that just said "ingredients in your order are unavailable. Please edit your order." It didn't indicate which items were unavailable. So I got back in. Waited for maybe 15 minutes because they had only one register open during a busy time. When I finally got up to the register and ordered, the cashier said they were out of avocados. It's a little ridiculous that at 4pm, they're out of avocados already. First time going to that Panera, & will definitely be the last!
