Was i wrong?

So i haven’t eaten at chipotle in 5-6 months. Used to eat there 1-2 times a week but as the prices were growing and the portions were shrinking, i just stopped going. They sent me a promotion to come back and I though ok, maybe it has improved. So i go by the store and start my order, everything looks good, but then i see they dont have any pico. I see its over on the mobile line and figured she would grab it from there. The staff flat out refused. I wasnt rude, didnt raise my voice or demand anything. I used to work service industry and always found being calm was the easiest way to get staff to help. She continued to refuse insisting they were out of pico even though i could see a full tub on the mobile order line.

So i asked her to set that bowl to the side and i said that i would put in a mobile order. She then threw the bowl away. I hate to waste the food and I dont really understand what happened. Can anyone explain it? Why wouldn’t she just get it from the other line instead of throwing the whole bowl away?
