First of all, are you sure level was FULL after the service??? Search how to measure oil level properly (it's not when you're moving). To monitor consumption, make sure level is full after a service and go from there. I'd buy a quart and top it off myself (you can search for that too), but many feel they're dealing with rocket science and are afraid to do it. You can also have dealer do it if you don't mind the hassle.
Second of all, that consumption is not abnormal at that early mileage, so don't worry about it. But my guess is your level wasn't full after the service. Good luck.
