SARA BROOKE CURTIS: An interesting thing with ‘enjoy’ is that it's become so common, because it’s so normal, so many people do it in all the different restaurants, to such an extent that there are restaurants that you could not say 'enjoy'. That was their biggest pet peeve, was saying ‘enjoy’. And it was massive. 
HZ: Why? 
SARA BROOKE CURTIS: Because they didn't want their servers to act like robots and they thought that if you said 'enjoy' that people would feel like they're anywhere, and that you're not expressing anything; you're just saying this thing that people say all the time. 
HZ: Where does it come from? Is there this cabal like the Pantone colour thing where it's like, "This year everyone will be wearing forest green" - is there that for service vocabulary?
SARA BROOKE CURTIS: Yeah, I think there is. I really do think there is.
