I would leave the shop not taking my goods with me, having not accepted the choice.
Neither STEEM nor SBD has a real value to me, it's virtual money only which I use to reward others. I never paid a bot or such. (No, neither the two accounts which voted for this comment within the last 4 hours. Those are paid by their owner.)
It's an interesting perspective and thanks for your feedback. What would it take for either currency to "have real value" to you?
Unlike other commentators I'm not into investment stuff. Not at all. Maybe that's explanation enough.
If not: I never was here for more than blogging actually. I'm happy to reward others but taking money out of this is a mere theoretical idea to me. I have some history of unemployment and monetary wealth is something I never had. I'm messy when it comes to handling money - there's no need to add more triggers.
You don't go to stores asking if you could pay with play money (like Monopoly's for example), do you?
Thanks for your feedback and sharing your perspective :) Like you I also came to steemit for blogging... then I stayed for the community.
