This is a short video of a man in khakis and a sports coat trying to grind a rail on a Lime electric scooter. Based on the way he lands on that rail, I'm guessing Chet here learned a valuable lesson about how not to spend his lunch breaks in the future. In this case, almost finishing a whole margarita then deciding a couple electric scooter tricks on his way back to the brokerage office is a good idea.
Keep going for the full video, complete with painful recovery.
Thanks to David R, who informed me he can't wait for the inevitable electric scooter trick fails compilation video. God, same here.
