I have and have had Goldens and Labs. Since I have had to train by myself a large percentage of the time, and especially when I first started in field work, I relied a lot on drills. All of my dogs have thrived on them and looked forward to them. It is especially rewarding when old retired FC-AFC dogs start acting like pups when they know they are going to get to run some favorite drills. Again, since I was training by myself, there were no fliers to jazz them up, so I tried to make the drills not only educational but challenging and enjoyable. I think the attitude of the trainer is a very important component to having a dog that loves to do drills. If you are an athlete, think about the coaches that really got you fired up to go out and work hard during scrimmages compared to those that turned drills into a form of punishment. If you are a scholar, think about those teachers that challenged you and made a subject one of your favorites. If you personally are bored running a dog on a drill, this is reflected in the dog. Be creative, keep them on their toes and thinking, and my Goldens have never worn a bandana. I did have one Lab that considered it, but only briefly.
