&quot;The service provided by Lyft is not the taxi ride, but the arrangement of the taxi ride.&quot;<p>You are right.  I was wrong about how Lyft&#x27;s customer agreement works.  I looked up the Lyft T&amp;Cs[0] and they specifically say:<p>&quot;In exchange for permitting you to offer your Services through the Lyft Platform and marketplace as a Driver, you agree to pay Lyft (and permit Lyft to retain) a fee of up to 20% (the “Administrative Fee”) of the Ride Fees paid by Riders for such Services.&quot;<p>This makes it clear that Lyft is acting as an agent (like eBay) not as a principal (like Tarsnap).<p>[0] <a href="https:&#x2F;&#x2F;www.lyft.com&#x2F;terms" rel="nofollow">https:&#x2F;&#x2F;www.lyft.com&#x2F;terms</a>
