I'm going to tell a first-time sushi eater that the wasabi is guacamole
Why would you mislead someone like that?
It's because I want to have a good laugh at dinner at the restaurant.
Playing a prank on someone can spoil the relationship between you and the person or it may spoils the persons mood. Rather than being insincere, make sure the person knows what they're doing before they try it.
I'm going to do that. Thanks for the advice, sorry I wasn't being so mature earlier.
It is good you realized how this would have ended. Spicy foods aren't for everyone, she would have avoided sushi for the rest of her life.
