I pushed my way past him after he didn't move when I was trying to get back to my seat.
He says, "Dude you just went all UFC on me".
I obligatorily replied, "If I actually went UFC on you, you'd know it."
"I don't think you know how to go UFC on anybody."
Smile and ignore.
"I said, I don't think you'd know how to go UFC on anybody."
"This is a classy bar, not a UFC bar. Don't you think?"
He then asks me to repeat myself, backs down and tells me that he's bartender at The Chalet, invites me down and disappears into a corner. This posturing stuff seriously cracks me up.
