A Conversation at Starbucks

In a line at Starbucks yesterday:

"It cost me $50.00 to fill up my tank."
Grunt. "Cost me $75. Did you see that show about Tesla?"
"The car. That's cool."
Admiringly: "Guy was pretty smart, too."
In agreement "Yeah."
"Bet we coulda had electric cars earlier. Tesla knew a lot."
"Yep."
