Worst service by Panera standards. How hard is it to make a drink in the correct size when there is only one size listed on the menu. When I asked about the error, they made me go back in li e to speak to the person at the cash register like I was making it up.
When they person brought my correct drink there was no apology for recognition of the mistake.
Basically to fix their error, the poured the drink into a larger cup and filled the rest up with milk.
The sign of true lazy workers.
