I&#x27;ve heard stories of Uber drivers demanding cash tips out of customers and giving low ratings to any customers who decline (IIRC, Uber&#x27;s TOS forbids this, but that&#x27;s almost impossible to enforce).<p>That doesn&#x27;t happen with Lyft: because tipping is built into the app, nobody asks for cash.<p>I don&#x27;t carry cash, so I&#x27;d be screwed if I rode Uber and a driver threatened me with a 1-star rating if I didn&#x27;t fork over cash.
