Or, avoid the whole problem by eliminating tipping altogether (please!). Charge a fair and honest price where you can compensate contract workers enough to incentivize them to work for you in the first place (no surprises), and customers will appreciate not feeling the pressure to figure out what an appropriate tip might be. Use feedback/ratings to reward exceptional service. As an added bonus, you eliminate the discriminatory problems of certain classes of people earning more tips than others for reasons unrelated to service.
