Resolution = easy... in that we're no longer going to work with them.
The explanation we received was that "an employee of theirs, whose first name they gave us but whose last name they 'could not remember' was given the order and given $$$ to go shopping." Evidently the employee either had permission to source items ordered where they saw fit, or, there was not any oversight and checking of what was purchased before the order was delivered to their customer. Neither bodes terribly well in terms of my confidence to entrust them with our reputation, something which we've worked fastidiously for the last 7 years to build and maintain.
They claim that this was an isolated incident, which perhaps it was, but still, some things don't add up: you give staff $ to go shopping, you don't check receipts, you don't know where they got things from, etc?
If anyone wants our food, contact us directly, we're more than happy to make stuff and pack/provision things to go.
