According to this authoritative source, a small tip paid through the sanitized process of an app is often appreciated (so your Uber driver doesn't get sick from that benjamin you hand him, so never tip a cash hundred). But, you may ask, and this scribe will answer: what makes Uber drivers most happy while they are starving?
You telling them that they ought to "stay safe and stay healthy"! And please don't forget to thank them for even showing up! You don't have to tip if you do! Your gracious comment alluding to how much you care for them will make their day. And will instantaneously make them forget that you just bilked them out of their own money by taking you on your $2.80 shorty.
P. S. Please do read the comments to the original article.
