What should I do if a Shaafi' invites me and serves prawns?

Answer

You will better understand the answer from the following question: If a Maaliki invites you to a meal, will you eat the meat if you know that the meat is of a bush rat or of a lizard or of a snake? These animals are halaal for Maalikis. Also, if you know that the Shaafi' is serving hyena or fox meat, will you eat it? In short, it is not permissible for a Hanafi' to eat anything which is Haraam in the Hanafi Math-hab.
