Did you pay exactly the same amount in btc as you would have in fiat?

I had an idea I mentioned on here once (hard to dig up or I'd link it) that I call "take 10" in my head -- the idea was that, if you're selling stuff ( goods, services) that you offer a 10% discount if they pay you in btc. That's not too much of a haircut, usually, and seems like a good way to begin to bootstrap the circular economy.

I wonder now if there's another side to it, for orange-pilling purposes: the 10% is a bonus that you could offer to pay for someone to accept btc who doesn't already? In other words: I'd like to pay in btc, I'll give you 10% more (this time -- or for a few times) if you accept payment in btc.

Obviously not everyone has the funds avail to make that deal, but it might be a solid orange-pilling strategy. Most of the people I talk to don't want to complicate their own lives with weird internet money, but for a 10% premium? Hmm.
