Some of you guys have nailed it!!
It's funny, but I have an ongoing
Net54 thread about my observations from the front lines of card shows, and I can say without question that
99% of the showgoers and dealers I approach have the same look on their faces
(as they look up from their phones) when I start engaging them,
"Wait, is this human being actually trying to talk to me in person...and not text...or Insta or Facebook me??!! I'm not ready for this. What am I supposed to do???"
