The answer to this question is unfortunately inconclusive. Some drivers seem to know about tipping before delivery, while others do not seem to be aware of the custom.
A study done by the Pew Research Center found that 62 percent of U.S. adults say they have tipped someone in a restaurant in the past year, but the custom varies across industries.
In the restaurant industry, tipping is more common than in other industries, with 87 percent of respondents saying they have tipped someone in a restaurant. In the food delivery industry, however, tipping is less common, with only about half of respondents reporting having tipped someone in the past year.
So, it seems that some Uber Eats drivers are more familiar with tipping than others. However, it is still unknown whether or not drivers are tipped based on the quality of the delivery or the total amount of food ordered.
Therefore, it is important to experiment a little and see what works best for you. Some tips that have been suggested include leaving a dollar or two in the tip jar, or writing a quick note to the driver thanking them for their great service.
