How do I deal with the toughest critic in the world at my business?

He is the toughest critic I've seen, he's reviewing the dancers, the experience he's had here and the bar. The only thing I'm worried about is that douchebag of a server I have working for me named Davis. I know that douche is gonna try to prank that critic

why do you want to deal with him at all.

ok try wearing a funny smile every time you see him. ask others to do same
