If you went to a trading card show and saw a vendor that accepted bitcoin, how likely would you spend sats to support that business owner?

I have a friend who is going to a big card show this weekend to sell a majority of his collection and spread the word about his side business (already managing a auto parts shop full time, he busts his butt). He let's me pay in sats when I buy from him, but I suggested he throw up his QR code and let people know he accepts btc as payment. I know there's people out there that like to honor the white paper like me and use it as a p2p cash system, so I wanted the communities take on taking opportunities to spend sats on stuff. Tyia
