Wedding Rehearsal Dinner Etiquette My Fiance Hired An Etiquette/table Manners Instructor For Our Wedding's Rehearsal Dinner. Is This Tacky?

My fiance hired an etiquette/table manners instructor for our Wedding's rehearsal dinner. Is this tacky? - wedding rehearsal dinner etiquette

Our rehearsals dinner tomorrow night for our wedding. My wife says that my family do not have good table manners and wants to make sure they eat in an acceptable manner during the welcome dinner on Saturday evening for the wedding. So I hired a trainer for $ 1,000, with a non-non-refundable deposit of $ 500.

I mean, of course, my family, fart jokes, which feed gas from several holes, but the immediate family does not? Is it really necessary for my Uncle Ernie knows his salad fork, fork? When my wife asked me before this decision?
