> is a useful incentive for good, quick service This is frequently said, but has anyone done any work to show that it's actually true? That tips work as an incentive for measurably better or improved service? Or to what degree it is true? Just wondering. I have a lot of friends in the service industry and, like people in many other careers, beyond a particular baseline of compensation and satisfaction, it seems that good performance is as much about intrinsic motivations as it is about extrinsic factors. The best people often simply want to do a good job. If the tips or overall comp isn't satisfactory, they either find a different place to work or take additional shifts at another bar or restaurant.
