Yes. Call service desk. They don't have all kind of baked goodies..Better to go in person.
Call during biz hours. You may have to be persistent as the warehouses are normally quite busy. And, I'm not sure they even have extensions in the Bakery Dept. But ask for a manager if all else fails!
Costco opens at 10:00 AM. Try calling them or ask the customer service desk to connect you.
You probably need to call during business hours. When they are open there is a directory that will take you to different departments.
