It's possible. They probably checked to see if they spun smoothly, and left them alone if so. Take your wheels off and spin the hub axles by hand. Smooth? A little gritty? Even if they are smooth, if it's old grease, it won't protect as well as fresh grease. Look under the bottom headset race, the bottom bracket shell, and the hub ends. Is there/was there black road grime? Or is/was fresh grease apparent? If the former, they probably weren't serviced.
