There are some debit cards tied to BTC that are basically instant withdrawal. You move your SBD to an exchange and sell it for BTC. Then transfer the BTC to the debit card. Now you can go buy groceries or whatever with the card. I have not tested this as I'm purely trying to accumulate more crypto right now so pulling any wouldn't make sense, but do a little digging and you will find a solution like this.
Feel like @ackza has shown a post or two showing this done. Even pulling cash at the ATM that was SBD just a little bit before.
