Is it possible to, without any extra knowledge, send a transaction back to whoever sent you monero?

In say, bitcoin, I know the address of whoever sent me btc, so I can send something back to them without them providing us their address “explicitly”. Can something similar be done in the monero protocol?

    I feel like this would defeat the anonymous factor of monero, but am eager to see if there’s a particular wallet or other tool that could achieve something similiar.

      Don’t see how it would, if party A can send funds anonymously to party B, then why can’t party B send funds anonymously to party A. A simple implementation would be to just put a new “(return) address” with each transaction.

      Indeed would introduce blockchain bloat. I do feel that this might be an important feature though. Say I need to pay before I can fill up my car, no one knows exactly how much gas I will be buying. I"d like to pay 1XMR and have the unused remainder sent back to me. Sure, not fully trustless but fine for small transactions.
